The Taff Vale Railway (TVR) was a standard gauge railway in South Wales, built to serve the iron and coal industries around Merthyr, and to connect them with docks in Cardiff. It was opened in stages in 1840 and 1841.
In the railway's first years, the coal mining industries expanded considerably, and the Taff Vale Railway soon opened branches in the Rhondda valleys and the Cynon Valley, and the conveyance of coal for export and for transport away from South Wales began to dominate. The docks in Cardiff and the approach railway became extremely congested, and alternatives were sought, and competing railway companies were encouraged to enter the trade.
Further branch lines were built, and the Company used "motor cars" (steam railway passenger coaches) from 1903 to encourage local passenger travel.
In 1922 the Taff Vale Railway was a constituent of the new Great Western Railway at the "Grouping" of the railways, imposing its own character on the larger organisation. The decline in the coal and iron industries took its toll on the mainstay of the network, but passenger trains operate at the present day on most of the main line sections,

Before the Taff Vale Railway
Coal mining and iron smelting had been carried out on a small scale in South Wales down to the eighteenth century; it was encouraged by the plentiful availability of coal, at first at a shallow depth; timber (for pit props, and for charcoal); and limestone (for fluxing). The coal was primarily used in iron production, and it was only gradually that surplus coal began to be used for power (in industrial stationary steam engines) and for domestic use.
In time coke replaced charcoal in the smelting process. The availability of the raw materials at the heads of the South Wales valleys led to a number of ironworks being founded there between 1750 and 1800; these included the Cyfarthfa Ironworks, Plymouth Ironworks, and Dowlais Ironworks works in the Merthyr Tydfil area.
A major difficulty was transport; conveying the finished product away to market was effected by coastal shipping, but the primitive road network made reaching the seaboard expensive and difficult; and the limestone, plentiful as it was, was located some distance north of the location of the ironworks.
In 1767 Anthony Bacon of Cyfarthfa persuaded his fellow ironmasters to join in a scheme to build a trunk roadway from Merthyr Tydfil to Cardiff. He used mule-trains.
A solution to the difficulty of local transport around the area of the ironworks was the tramroad. Wooden railways had been extensively used elsewhere, but seem not to have been much used in South Wales. The local tramroads were almost all short distance plateways (in which the rails are L-shaped plates, carrying wagons with plain wheels), and in many cases were simple extensions of plateways used underground in mines. 
Canals were built down some of the valleys, to bring the iron down to the coast for shipping elsewhere. The Glamorganshire Canal was opened in 1794; it ran from Merthyr Tydfil to Cardiff, a distance of 25 miles. Local mine owners (within four miles of the canal) were authorised to build tramroads to the canal. At least 400 miles of tramroad was built under this and similar arrangements before the coming of modern railways. 200,000 tons of coal were brought down by the canal in 1839 to the dock that became Bute West Dock.
The Penydarren engine
In 1802 the Merthyr Tramroad was opened, connecting the Dowlais and other ironworks with the Glamorganshire Canal. Richard Trevithick was employed at Penydarren Ironworks, served by the tramroad, and he built a steam locomotive engine. In 1804 a demonstration run took place in which ten tons of iron and 70 persons were transported nine miles. This was the first use of a steam locomotive engine in the world.[note 1] However many of the cast iron tramplates were broken due to the weight of the engine.
A railway proposed
For the first decades of the nineteenth century, the transport situation for Merthyr and the surrounding area changed relatively little; the Glamorganshire Canal prospered, but became overwhelmed by the volume of trade. Tramways continued with horse haulage and plateway track. Mule trains carried iron down the turnpike road.
Edge railways began to be made elsewhere in the country; the Stockton and Darlington Railway of 1825 and the Liverpool and Manchester Railway of 1830 showed what current technology was capable of.
Taff Vale Railway planned
Early in 1835 Anthony Hill, owner of the Plymouth Iron Works at Merthyr, asked the engineer Isambard Kingdom Brunel, a personal friend, to estimate the cost of building a railway from Merthyr to Bute Docks in Cardiff. Brunel's estimate was £190,649. Local industrialists held a meeting, chaired by John Josiah Guest, MP for Merthyr, at the Castle Inn there.
In fact Brunel soon (in 1836) revised his estimate upwards, to £286,031, to accommodate improved gradients, mineral branches and shipping staithes.
Act of Parliament
The promoters agreed to go forward with a Parliamentary Bill in the 1836 session. The Glamorganshire Canal opposed the Bill, but it was passed, and obtained the Royal Assent on 21 June 1836. The Taff Vale Railway was incorporated with capital of £300,000. The directors were Josiah Guest (who became its first chairman), Walter Coffin, Edward Lee, Thomas Guest, Thomas Guppy, Thomas Powell, Christopher James, Thomas Carlisle, Henry Rudhall, William Wait, William Watson, and Peter Maze.
The act authorised a railway from Merthyr Tydfil to Cardiff, with several branches: to connect with the tramroad to Dowlais and other ironworks nearby; to collieries at Llancaiach; to the tramroad serving Dinas collieries (in the Rhondda); and to Cogan Pill. Company profits were limited to 7%; this could be augmented to 9% if the tolls for use of the line were substantially reduced. Independent carriers as well as the Company itself were potentially able to use the line. The Act also limited the speed of the trains on the line to 12 mph (19 km/h), with stiff penalties for any speeding. (These two clauses were repealed by Act of 1840.) Locomotive operation and the carriage of passengers were permitted by the Act of 1836.
The Merthyr terminus was to be on an open space south of the town, between the River Taff and the Cardiff Road. The Cardiff terminal was to be at or near the Ship Canal which the Marquis of Bute proposed to build. This became Bute West Dock; he had obtained powers to build it in 1830 but had held off from actually doing so.
Isambard Kingdom Brunel, as the engineer for the line, designed it as a standard gauge line. He told the directors,
As regards the gauge or width of the rails, I see no reason in our case for deviating materially from the ordinary width of 4' 8½". The general gradients, the inclined planes, and still more the nature and the immediate extent of the peculiar class of traffic to which the line must always be devoted, not only render high speeds unnecessary, but must almost prevent their being attempted, while the same causes operate to diminish any advantage that may be gained in reducing friction by increased diameter of carriage wheels.[note 2] The curves also which the nature of the ground render unavoidable would be unfit for a wider gauge…
Construction and opening of the first main line
The construction of the line posed no great engineering challenges due to its course following the valley of the River Taff. The line was 24 1⁄4 miles in length. At Quaker's Yard there was a sudden steep change of ground level, and Brunel used 50 hp stationary winding engines; the inclined section was half a mile in length with gradients of 1 in 19 and 1 in 22. Locomotives did not ascend the incline. There was a 1 in 13 gradient on the Pwllyrhebog branch, near Tonypandy; it too was rope worked with special locomotives. Inevitably there were some stiff gradients elsewhere. There were two stone viaducts on the route: the first, at Pontypridd, crosses the River Rhondda, and the second bridges the Taff valley between Goetre Coed and Quaker's Yard.
As well as the avoiding the use of the broad gauge, Brunel adopted a different form of track for the line: "parallel rails" weighing 55 lbs per yard, fixed in chairs with compressed wooden keys. The chairs were fixed to transverse sleepers by screws inserted prior to laying, "ensuring accuracy of gauge".
A ceremonial opening of the line between Cardiff and Navigation House (Abercynon) took place on 8 October 1840, when the Directors and Shareholders travelled on the line; the full public opening of that section was on 9 October 1840. On 20 April 1841 the line was inspected by Sir Frederick Smith for the Board of Trade, and on 21 April 1841 the main line was opened throughout to Merthyr.[note 3] Passenger stations were at Cardiff, Llandaff, Pentyrch (later Radyr), Taff's Well, Newbridge (later Pontypridd), Navigation House, Troedyrhiw and Merthyr. There were two passenger trains each way daily, seven days a week. The line was single throughout with passing places at the stations. On double track sections and at crossing loops, right-hand running was employed for several years.
A mineral branch from Pontypridd to Dinas (Rhondda) opened in June 1841.
The Llancaiach Branch branch was authorised in the original Act for the TVR. It opened on 25 November 1841 for mineral traffic only, from Stormstown south of Abercynon to three adjacent collieries at Llancaiach. There was a self-acting rope worked incline 600 yards long on a 1 in 8 gradient. Use of the line was disappointing, traders finding that the charges on the canal were substantially lower.
The company hesitated to build the authorised branch to the tramroad to Dowlais, and the clause in the Act enabled the Dowlais Iron Company to take over the construction and the branch, which they did.
First years of operation
The line was open between Merthyr and Cardiff, but almost immediately thought was given to improving the capacity of the main line, and of serving the coal production of adjacent valleys.
The line was originally single, except for the Quaker's Yard and Llancaiach inclines, which were double; Cardiff to Taff's Well was doubled in 1846, and through to Navigation House in 1847. The doubling was completed to Merthyr in 1862.
Extending to Aberdare
The original purpose of the Taff Vale Railway had been deeply connected with the ironworks of Merthyr. In the years immediately following the railway's authorisation, the rich seams of high quality coal in the Aberdare area came into prominence, and began to outshine the Merthyr trade. Sixteen steam coal pits were sunk there between 1840 and 1853. Those collieries required transport to the sea, and the proprietors of the Taff Vale Railway responded by sponsoring the Aberdare Railway, a nominal independent company.
The Aberdare Railway was incorporated on 31 July 1845 to make a 7 1⁄2 mile branch from Navigation House to Aberdare. It was worked by the Taff Vale from the outset and leased to it from 1 January 1847. It opened for passenger and goods and mineral traffic on 6 August 1846. Navigation House station was renamed Aberdare Junction on the opening of the branch. There was a 49 chain branch off the Aberdare line from Cwmbach to Abernant colliery, also opened in 1846; it crossed the River Cynon to get access.
Left hand running
In 1847 the Newport, Abergavenny and Hereford Railway obtained powers to build its Taff Vale Extension Railway westwards from Pontypool Quaker's Yard. to connect the TVR. This would be the first connection with the rest of the narrow (standard) gauge railway network; the TVR reviewed its policy of right-hand running and decided to change to left-hand running in preparation for the connection.
Taff Vale Extension Railway
The Newport, Abergavenny and Hereford Railway reached Quaker's Yard on 11 January 1858, and made a connection with the TVR there. This gave a route for minerals from the TVR network to reach much further afield, but reduced the haul length on the TVR system. The Taff Vale Extension Railway was later extended to Middle Duffryn, near Aberdare, opening in April 1864.[note 4] The extension crossed the Llancaiach colliery sections of the TVR on the level ,and Llancaiach coal was transported via Quakers Yard on the TVER in preference to using the Llancaiach line inclined plane.
The coalfield around Aberdare was proving to have abundant resources of high quality coal, and the Taff Vale Extension line was able to take the output direct to London (via Hereford--the South Wales Main Line was still broad gauge) and to Birkenhead and Southampton, where bunkering of sea-going ships was an important market.
The Rhondda valleys too began to be the source of excellent coal, and that trade started to exceed that of Merthyr. The branch line from Newbridge (Pontypridd) to the tramroad leading to the collieries called Dinas had been opened in 1841, and this stimulated interest in mining in the valley.
Spurred by the threat of a possible broad gauge line from Ely, the TVR obtained authorisation on 26 August 1846 for the Rhondda Fawr Valley Extension, in time reaching what is now Treherbert, opening to there on 7 August 1856. Passenger services were not started until 7 January 1863.
In 1849 the Taff Vale offered a £500 premium for proving the existence of deep-seam coal in the Treherbert area. At the same time a 77 chain extension from Porth to Ynyshir was opened for mineral traffic; that stub was extended to Ferndale in 1856 and later to Maerdy, which at 900 feet above sea level was the most elevated location on the Taff Vale system.
In 1854 the Eirw Branch was opened; under a mile long it left the Rhondda line at Trehafod to serve nearby collieries.
In 1857 the TVR board authorised the doubling of the Rhondda Fawr as far as Porth; by February 1858 eight collieries were sending their coal down the extension of the Rhondda branch.
In the subsidiary Rhondda valley, the Rhondda Fach, the line was opened from Porth to Ferndale in the summer of 1876, and to Maerdy not until 1889.
The Pwllyrhebog branch (as it became known) was authorised in 1857 to reach into Cwm Clydach from Tonypandy. Its actual construction was much delayed, a contract being let in December 1861; it was opened early in 1863.
It climbed away from the Rhondda very steeply, on a 1 in 13 gradient for 3⁄4 mile and then on to Blaenclydach.
At first the Pwllyrhebog incline was worked on the balanced load system, and the TVR refused to install a stationary engine, although increasing volumes of output were putting a strain on the capacity of the system.
At this stage the Pwllyrhebog branch served two collieries, Cwm Clydach and Blaen Clydach, but in 1871 Thomas, Riches & Co sank an important new pit further up the Clydach Valley at Clydach Vale. In November 1871 the TVR agreed to extend the Pwllyrhebog branch to the new pit; in fact the colliery company built the line and transferred it when completed to the TVR. The Company also undertook to send all their traffic out via the TVR.
The new pit was at a much higher altitude even than the previous connections, and a zigzag arrangement immediately above the Pwllyrhebog incline was necessary to gain further height.[note 5]
An Act of 13 July 1899 formalised the ownership.
Writing in 1951, Casserley refers to a later time when a stationary engine had been installed:
The incline was worked on the counter-balance system, but there were two separate ropes for the ascending and descending trains, in contrast to the endless loop rope more commonly used in this situation.
The winding engine worked at a pressure of 25 lb. per sq. in., and the speed on the incline was about 5 m.p.h. The Taff Vale Railway used three 0-6-0 tank engines specially designed for the incline, acquired from Kitsons in 1884. They were had taper boilers to ensure that the firebox crown was covered when on the gradient; Casserley speculates that they probably were the first engines anywhere with taper boilers. The TVR gave them nos. 141 to 143; after 1923 they became GWR nos. 792 to 794. and were nos. 193 to 195 in British Railways days. Under the GWR a spare engine was kept as a standby; it was a standard pannier tank, No. 7722. Casserley does not explain how the firebox crown was kept covered in the case of this locomotive..
In 1889 the line was extended privately to Clydach Colliery, making a little over two miles in all; the private extension was acquired by the TVR in 1896.
In 1867 a Bill was presented for a railway from Treherbert to Hirwain (Hirwaun from 1926). The Rhondda Valley and Hirwain Railway was authorised by Act of 12 August 1867. It was nominally independent. It opened a short section from immediately north-west of Treherbert to Blaenrhondda, with a short spur to Blaencwm Colliery, in June 1878 for mineral traffic only. It abandoned its ambition to cross the 1,561 feet pass to Hirwain, and leased its line to the Taff Vale Railway from 1878: on 26 August 1889 it was absorbed by the Taff Vale.
Widening the main line
An act passed in 1857 gave the railway authority for a number of improvements over the coming years. The line was doubled throughout from 1858 to 1862, and later quadrupled between Pontypridd and Cardiff to accommodate the growth in traffic. New viaducts were built alongside the existing structures at Pontypridd and Quaker's Yard to carry the second line. In 1864 work started on bypassing the incline with a gentler bank (but still steep and 1 in 40). This required significant earthworks, and inclement weather meant that it was not completed until August 1867. Top of Incline station had already closed in 1858, replaced with a new station at Quaker's Yard. Pontypridd station was greatly extended during the 1860s.
Cardiff docks and Penarth
The Cogan Pill branch authorised in the original Act was deferred, chiefly due to considerable opposition by the Marquis of Bute. Instead the Company was coerced into accepting a long lease of Bute West Dock; in 1848 a branch, known as the East Branch, was opened to connect to it. The lease was expensive and not entirely convenient. The Taff Vale was further put out when the rival Rhymney Railway was given access to the east side of the East Dock on considerably more favourable terms. This dock was commissioned in stages between 1855 and 1859, and the Taff Vale was excluded from using it, except as a sub-tenant of the Rhymney. From 1866 the Taff Vale was permitted access to the East Dock, but it had to run over the Rhymney Railway from Crockherbtown Junction, just north of the present-day Queen Street station, to reach it, paying the Rhymney for the privilege. Moreover congestion, for shipping and for railways, in the Bute Docks was becoming an increasing problem.
These dissatisfactions led to the company sponsoring the Ely Tidal Harbour and Railway, which was authorised by Parliament on 21 July 1856. This was to construct a tidal harbour at Penarth, south-west of Cardiff, and an approach railway from Radyr on the Taff Vale line. The route was modified by an Act the following year, on 27 July 1857, and the name of the railway changed to the Penarth Harbour, Dock and Railway. The railway leading to Tidal Harbour east of Cardiff, was just over 6 miles long, was opened in August 1859, but the dock took much longer to complete: it was ready in 1865.
The Penarth scheme experienced determined hostility from the Bute docks interest, and there was protracted litigation over the validity of the powers; although the final outcome was in favour of the Taff Vale Railway, the House of Lords decision bound it to charge shipping rates no lower than the Cardiff rates. A major extension was later made, opening in 1884.
The opening of the Penarth Docks proved a huge benefit to the Taff Vale Railway, not only in bringing in direct revenue, but in easing congestion on the main line as mineral trains were diverted from Radyr. Enormous volumes were moved through the docks: 2.8 million tons in 1885. The Penarth Harbour, Dock and Railway was leased to the Taff Vale, although the owning company retained its independent existence until 1922.
In 1857 a competitive threat emerged when the Ely Valley Railway was incorporated, to build a broad gauge line from Llantrisant, on the South Wales Railway between Cardiff and Bridgend, towards the Rhondda valley. It opened in August 1860 as far as Tonyrefail, and in 1862 it was extended to Penygraig, close to the Taff Vale Railway at Tonypandy. It was leased to the Great Western Railway from 1 January 1861; the GWR wanted it as a source for locomotive coal, and the lease was independent of the local broad gauge railway, the South Wales Railway. 
The Taff Vale Railway saw this as a threat and promoted the nominally independent Llantrisant and Taff Vale Junction Railway, which obtained its Act of incorporation on 7 June 1861. It was to build from the Taff Vale main line near Treforest[note 6] to make a junction with the Ely Valley Railway at Maesaraul, near Llantrisant. The line opened in December 1863 for freight traffic. A passenger service was operated from Pontypridd to Llantrisant from 21 January 1875.
The nominally independent Cowbridge Railway was authorised on 29 July 1862, to build from the Great Western Railway (former South Wales Railway) station at Llantrisant to Cowbridge. This was another Taff Vale dependency as it failed to generate the necessary subscriptions to build the line itself. The line opened in February 1865. The GWR line was broad gauge, and the branch to Cowbridge was accessed from the Llantrisant and Taff Vale Junction Railway. Trains from Pontypridd ran over the final section of the Ely Valley Railway and across the South Wales Main Line to the Cowbridge Railway terminus, where they had to reverse to continue.
By-passing Quaker's Yard incline, and opening Pontypridd north curve
The incline at Quaker's Yard had become increasingly busy to the point of serious congestion, and in 1864 the decision was taken to by-pass it. A new route with a gradient of 1 in 40 was installed nearby and was commissioned in mid-1867. The TVR had running powers over the GWR Taff Vale Extension line from Quaker's Yard to Llancaiach and the mineral output from the mines there could now more conveniently be brought out via Quaker's Yard, avoiding the incline on the Llancaiach branch, which was closed except for a short section at the north end. A north curve at Pontypridd was opened in October 1872, also facilitating the transfer of mineral output between the branches of the TVR system.
There was intensive mining activity in the hills to the south of Aberdare, and the Vale of Neath Railway had already opened a branch there. In 1866 the Dare Valley Railway, incorporated 1863, was opened from Aberdare to the Bwllfa Colliery[note 7] in 1866. The line was worked by and leased to the TVR.
Iron production in South Wales peaked in 1871, after which the process was remorseless decline. An exception was at Dowlais, where the Bessemer process of steel making was instigated from 1865. This required a different quality of iron ore, not available locally, and the potential traffic flow of imported ore encouraged thoughts of improved railway connection. Several unsuccessful schemes were put forward, but a joint venture between the Rhymney Railway and the Great Western Railway (by now owner of the Taff Vale Extension line) resulted in the Taff Bargoed Joint Line. This opened on 10 January 1876 for goods and minerals from Taff Bargoed Junction, immediately west of Llancaiach station, to Dowlais. Passenger operation started on 1 February 1876.
The Taff Bargoed Joint Line had been authorised in 1867 and there were certain protections in its Act for the Taff Vale Railway, including running powers over it. In 1872 the TVR presented a Parliamentary Bill to build on that, making a new railway to Llancaiach, with new connections to the Taff Vale Extension line. The intention was to run to Dowlais over the Llancaiach line and the Taff Bargoed line. The TVR already had access to Dowlais over the Dowlais Railway, but this route seemed more attractive, linking in the Navigation Colliery, and possible traffic from the Taff Bargoed line itself.
In fact the terms of the running powers did not permit through running at Llancaiach and the TVR's intentions were frustrated when the GWR declined the facility, and the Llancaiach branch was not brought into full use.
Later extensions to the system
The TVR's original station in Merthyr at Plymouth Street was opened on 12 April 1841, and was a short distance south of the town. This was joined in 1853 by the High Street station of the Vale of Neath Railway. A short joint line (TVR and GWR) was built to connect the TVR line to the new station in 1877. A year later, in August 1878, the Taff Vale transferred all of its passenger services to the High Street station, and used Plymouth Street as a goods depot instead. High Street station thus became the only passenger station in Merthyr, and was used by a total of six separate companies prior to the 1923 grouping. The TVR also opened stations at Merthyr Vale in 1883 and Pentrebach in 1886.
A short branch from the Penarth Dock line to the town was opened on 20 February 1878. Known as the Penarth Extension Railway, it was a mile long, running up a gradient of 1 in 40 from Cogan Junction to Penarth Town.
Treferig Valley Railway, and the L&TVJR line
Seeking further expansion north of Llantrisant, the Taff Vale encouraged the formation of the Treferig Valley Railway, incorporated on 21 July 1879. This opened a 2 mile 56 chain branch from Treferig Junction, near Common Branch Junction on the Llantrisant and Taff Vale Junction line, to Treferig and Glyn Collieries in April 1883 for mineral trains only.
In 1865 the Ogmore Valley Railway was opened. It was a standard gauge line, and there appeared to be enormous potential to bring standard gauge mineral trains to Penarth. The Taff Vale obtained authority to build a north-west to south-east diagonal line across the Llantrisant and Taff Vale Junction Railway system to handle this traffic. Financial difficulties delayed construction, and in the meantime the South Wales main line of the GWR was converted to standard gauge.
Now a main line railway was available for the Ogmore Valley traffic via Bridgend, and at a stroke most of the (unbuilt) diagonal line was of little value. However there were severe penalties in the legislation if it were not constructed, so the TVR used delaying tactics. It was eventually built throughout: the section from Common Branch Junction to Waterhall Junction, between Radyr and Penarth, giving direct access to the docks opened in 1886 for goods and mineral traffic only.
The volume of mineral traffic exported through Penarth Docks had continued to grow, and capacity of the railway and of the docks was overwhelmed. On 23 April 1888 the Taff Vale Railway opened a branch railway to the Roath Dock, itself opened in 1887, on the east side of the Cardiff complex of docks. The line diverged from the main line at Roath Branch Junction and arched round the east of the built-up area of the city of Cardiff as it was at that time, connecting with the Cardiff Railway lines in the docks.
The Taff Vale Railway obtained powers to build a branch to collieries in the Clydach Valley in 1872, but then lost enthusiasm for the project when anticipated colliery development in the area did not materialise.
However Lady Windsor Colliery, near Ynysybwl, was sunk in 1885, and promised to be a substantial activity. The Taff Vale Railway decided to build a branch line to serve it. It ran from a north-facing junction a mile or so south of Abercynon to collieries near Llanwonno, some way west of Ynysybwl itself; the branch was 4 miles 67 chains in length and it opened for goods and mineral traffic in 1886, though some informal use may have taken place in 1884; the passenger service as far as Ynysybwl started from Aberdare Junction, (known as Abercynon from 1896) on 1 January 1890.
In 1900 a south curve connection to the main line was opened, but the TVR was concerned about congestion at Pontypridd, and held off from starting the southward passenger service. After a delay, a motor car (railmotor) passenger service connecting Pontypridd and Ynysybwl was started on 17 October 1904, the northward service to Abercynon being then discontinued.
The original Llancaiach branch had left the Merthyr main line at Stormstown Junction, just south of Abercynon, and crossed the River Taff and then swung east to reach its objective. It had opened in 1841. After a period of dormancy, in 1878 a deviation was built avoiding the rope-worked inclined, but due to a dispute over running rights with the GWR the new line was little used.
Several decades later other collieries required to be connected on the east side of the Taff, in particular Albion Colliery, in preparation, and productive from 1887, and Cardiff Dowlais Colliery, productive from 1889. The decision was taken to make a branch from a junction further south, in fact at Pont Shon Norton, at the northern margin of Pontypridd. This was opened in 1887 as far as Cilfynydd.
In 1900 the branch was extended northward to join the earlier Llancaiach branch, at Ynysdwr Junction; this was opened to traffic on 1 June 1900. A passenger service operated from Pontypridd to Nelson, on the TVR line a little short of the junction with the Taff Vale Extension line, and did not use the GWR Llancaiach station there.[note 8] A motor car (railmotor) service was inaugurated on 10 August 1904.
Cowbridge to Aberthaw
The Cowbridge and Aberthaw Railway was authorised on 12 August 1889 to build from the end of the Cowbridge Railway to Aberthaw on the Bristol Channel, where there were important limestone quarries. The Cowbridge terminus was not aligned to permit the extension, and a new Cowbridge passenger station was opened on the Aberthaw line, the old terminus reverting to goods status. The Aberthaw line opened on 1 October 1892. The little company was vested in the Taff Vale Railway effective from 1 January 1895. The opening of the Vale of Glamorgan Railway in 1895 abstracted much of the potential mineral traffic.
Relief lines were constructed at Pontypridd in the 1890s, enabling goods trains to pass the station, and wait for a path, without interfering with passenger trains. Between 1907 and 1914 the station was rebuilt as a single long island platform with numerous bays. This work included raising the level of the entire station by nearly 5 feet (1.5 m). The new station had over 8,200 square yards of platform, and passengers starting or finishing a journey there exceeded 10,000 daily by 1920.
Congestion was serious at Stormstown too, and layout enhancements were installed there in 1906; the opportunity was taken to shift Berw Road Platform from the site on to the Llancaiach branch.
The Taff Vale Railway had been the first railway to serve the valleys of South Wales, at first to chiefly handle the iron products of Merthyr, but soon to bring the coal output of the area served to the docks of Cardiff. As the coal production of the region grew so greatly, it was inevitable that competing companies would enter.
The Rhymney Railway was the main competitor to the Taff Vale in bringing coal down from the valleys. For many years, until 1871, this involved Rhymney Railway coal trains running over the Taff Vale main line from Walnut Tree to Cardiff. The line was extremely congested.
In 1867 the Rhymney Railway obtained running powers over the Taff Vale Extension line between Hengoed on the Rhymney system, through Aberdare to Hirwaun, giving it direct competitive access to the Aberdare coalfield.
Cardiff Dock congestion and Barry
The phenomenal increase in volume of coal shipped out of the various Cardiff docks had long been such that the capacity was overwhelmed. There were constant complaints that congestion on the railway, and in the harbour, resulted in unacceptable delays and costs. One outcome of the situation was the promotion and construction of docks at Barry, and the Barry Railway, which ran direct from the Rhondda collieries to Barry. The Barry Railway was authorised in 1884, and Barry Docks opened on 18 July 1889.
The Barry Railway went on to promote a direct Cardiff, Penarth and Barry Junction Railway, which would run direct and also have a roundabout line following the coast. The Taff Vale opposed this and promoted its own alternative lines. Parliament decided on a compromise, in which the Barry Railway could build the direct line from a junction with the Taff Vale and Cogan, and the Taff Vale would build the coastal route, from Penarth Town, joining the Barry Railway at Biglis Junction, near Cadoxton. The Taff Vale scheme was authorised by the Cardiff, Penarth and Barry Junction Railway Act of 6 August 1885. The line was ready and opened on 1 December 1887, but the junction connection at Biglis was not made at first; for the sake of diplomacy it had to wait until the Cogan connection of the Barry line was ready, and they both opened on 20 December 1888. Taff Vale passenger trains ran through to Biglis Junction station of the Barry Railway from August 1889. (The station was renamed Cadoxton on 1 June 1890). The Cardiff, Penarth and Barry Junction Railway became vested in the Taff Vale Railway by Act of 26 August 1889.
Pontypridd to Newport
The extensive and modern dock facilities at Newport were serving the Monmouthshire valleys well enough, but there was a natural desire to handle some of the profitable business of the Cardiff Valleys too. The docks at Newport were operated by the Alexandra (Newport and South Wales) Docks and Railway, the railway part of their operation being confined to the docks area. They encouraged the formation of a nominally independent railway, the[Pontypridd, Caerphilly and Newport Railway, authorised in 1878. The line ran from a junction immediately south of the Taff Vale Railway station at Pontypridd to near Caerphilly, relying on running powers from there over the Rhymney Railway and the Brecon and Merthyr Railway to reach Newport. The line was opened in July 1884. Seeing this as an opportunity, the Taff Vale worked the mineral trains for the PC&NR (until 1906).
Rhondda and Swansea Bay
Swansea docks too was expanding its facilities: the new Prince of Wales Dock opened in 1881; during construction the owners saw that attracting coal shipments from the Rhondda valley could be beneficial, and the result was the promotion of the Rhondda and Swansea Bay Railway, which was to run from Treherbert, at the head of the Rhondda Fawr, through a long tunnel to cross the watershed, and the down the valley of the River Afan. The construction of the tunnel took a long time, and the line opened in 1890.
The Bute Docks Company was created on 1 June 1887 when the Bute Docks properties were vested in the new company. In 1897 it succeeded in getting authorisation to build a railway, which became the Cardiff Railway, to build from Heath on the Rhymney Railway to Treforest on the Taff Vale Railway, and a southward line from Heath to the docks at Roath. It took until 1911 to construct he line from Heath as far as a point close to the Taff Vale line at Treforest, but the Taff Vale succeeded in fending off the incursion. In fact the connection was never made, and the Cardiff Railway never achieved its potential.
In the period 1870 to 1888 the dividend on the ordinary shares averaged 12 1⁄2 per cent.
The twentieth century
The emphasis throughout the nineteenth century existence of the TVR had been on mineral traffic. When Ammon Beasley became General Manager in 1891 he sought to increase the passenger income of the company, particularly in the face of street-running passenger tramcars. In 1903 he introduced steam "motor cars" on the TVR. These were self-contained passenger coaches incorporating a small steam engine; the intention was to adopt a low-cost means of serving wayside communities by opening very basic stopping places (referred to as "Platforms") and having a more frequent timetable.
Consideration was given to whether the "platforms" could be at ground level, accessed by folding steps on the vehicle, but the decision was taken to make them elevated.
The first experimental run was on the Penarth branch on 21 December 1903
The TVR used the system in both rural and suburban situations, and it was commercially successful for some time; the TVR had 19 steam railcars at the peak, with first and third class accommodation. They had the disadvantage of inflexibility at busy times, and the small traction units became worn out after a decade and a half. At that stage the TVR converted the coaches to push-and-pull control trailers, using small independent locomotives as the power unit.
As well as starting to use steam railcars in 1903, the TVR obtained Parliamentary powers in that year to install electric traction equipment. However the powers were never used.
Following World War I the government decided to restructure most of the railways of Great Britain into one or other of four large companies. The process was called the "grouping" and was legislated in the Railways Act 1921. The old Great Western and six of the South Wales railway companies were constituents of the new Great Western Railway. The other smaller railways in the GWR area were "subsidiaries". The Taff Vale Railway was the second largest constituent of the new Great Western Railway; the old GWR was the largest. The Taff Vale Railway was amalgamated into the putative new GWR on 1 January 1922.[note 9]
Immediately prior to the amalgamation, the trading position of the Taff Vale was (compared to the GWR in brackets):
Issued capital: £6.42 million (£101 million); net income in 1921 £464,654 (£6,188,433); annual dividend on ordinary stock in 1922 4% (7 1/4%); route length 112 miles (2,784 miles); number of employees 5,690 (91,985).
The Grouping meant that the competitive situation with the Rhymney Railway no longer existed, and in July 1928 a new connection was installed at Cardiff Queen Street to enable the Rhymney trains to use Queen Street instead of the unsatisfactory Parade station adjacent.
The production of steel at Dowlais ceased in 1930; the inward haul of iron ore had sustained the Cilfynydd line, and the GWR decided that the thinly patronised passenger service was unsustainable; it was taken off, and the line closed completely above Cilfynydd from 12 September 1932.
The main line railways of Great Britain were taken into nationalised ownership at the beginning of 1948, following the Transport Act, 1947. The former Taff Vale area became part of the Western Region of British Railways. The end of World War II had brought to notice what had become inefficient working methods, and British Railways immediately set about some closures.
The mineral line above Old Ynysybwl had never reached its potential, and was closed completely on 22 September 1949; the passenger was closed on 28 July 1952, and all ordinary traffic ceased in November 1959. Lady Windsor colliery continued in business, served from the Stormstown direction, until closure of the colliery on 26 March 1988 and of the mineral trains after 20 May 1988.[note 10]
The Pwllyrhebog branch was closed on 1 July 1951. The Pontypridd to Llanstrisant passenger service ceased on 31 March 1952; the goods service closed in 1959. The Cowbridge line closed to passengers on 26 November 1951.
In June 1952 a new connection was made at Taffs Well to the colliery at Nantgarw, enabling closure of the Cardiff Railway connection beyond Coryton.
By the 1960s more passenger closures took place, and the rationalisation of some over-provision of infrastructure was also implemented. The Aberdare branch was closed to passengers on 16 March 1964, and the line was singled in 1968. The Maerdy branch (Rhondda Fach) passenger service was withdrawn on 15 June 1964, and the branch was singled later that year. The Blaenrhondda branch was closed in 1966, and in June 1966 the Bute Road branch was singled. The Penarth branch was singled in February 1967, and the west-to-north curve at Pontypridd was closed on 5 August 1968.
The Roath branch was closed on 6 May 1968. In addition the now-freight-only Cowbridge line closed completely in November 1965 (except for iron ore traffic to Llanharry, until 1975. The Penarth to Cadoxton line closed completely on 6 May 1968, together with the Roath Dock branch on the same day.
Closures in the mid 20th century left the Taff Vale as the only railway route to Merthyr Tydfil. Plymouth Street goods station was closed in 1968. The line from Black Lion signal box (Merthyr Vale) to Merthyr Tydfil was singled in February 1971. As mineral traffic declined, the quadruple track south of Pontypridd was unnecessary, and it was reduced to double line in 1980.
On 10 August 1973 the extremity of the Aberdare branch was altered; approaching from Abercynon, the line crossed the River Cynon at Cwmbach, along the alignment of the much earlier Cwmbach colliery spur, and joined the former Taff Vale Extension and Vale of Neath line into Aberdare. The line from the point of divergence to Aberdare TVR was closed.
The network today
The main routes of the Taff Vale Railway are in action today with passenger operation dominant. Merthyr, Aberdare,[note 11] and Treherbert have train services to Cardiff Queen Street. The Cardiff Bay branch operates the majority of the former Cardiff Docks branch. The Penarth branch and the Radyr to Ninian Park line complete the surviving passenger routes. In 2017 the passenger operation is under the management of Arriva Trains Wales.
There is a very limited freight service, consisting only of trains from Tower Colliery, above Aberdare.
On 19 October 1878 an empty passenger train was turning on the Pontypridd triangle; it was propelling wrong line from North Junction to Rhondda Cutting Junction; it collided with a down Rhondda train; there were thirteen fatalities.
On 12 August 1893, a defect on a locomotive caused a passenger train to derail at Treforest, Llantrisant Junction. Thirteen people were killed and twelve were injured. The 3.50 p.m. train from Merthyr to Cardiff derailed. The train was conveying through coaches from Aberystwyth. A pin forming part of the suspension of the locomotive fractured and the locomotive collapsed, and six passenger vehicles ran down the embankment and were smashed.
On 23 January 1911, a passenger train ran into the rear of a coal train at Coke Ovens, near Pontypridd. Eleven people were killed and five were seriously injured. The accident was due to irregularities in the block working by the signalman, who forgot that he had admitted the first train into the section and had not received Train Out of Section for it. The block instruments were of the two-position type.

Prior to 1873, Taff Vale’s locomotives were designed and built by outside contractors. The TVR’s Locomotive Superintendents were:
- Taff Vale Railway A class
- Taff Vale Railway H class
- Taff Vale Railway O1 class
- Taff Vale Railway O2 class
- Taff Vale Railway O3 class
- Taff Vale Railway O4 class
- Taff Vale Railway U class
- Taff Vale Railway U1 class
Lawsuit against a trade union
In 1901 the Taff Vale Railway Company successfully sued the Amalgamated Society of Railway Servants, a trade union, for damages due to losses accrued during a strike by their members, who were seeking to compel the company to recognise the union. The Company was awarded £23,000 by decision of the court, reversing the belief that trade unions were immune to damages from the actions of their members. Following the change of government in 1906, the Trade Disputes Act 1906 was passed, giving trade unions immunity from such claims.
Preserved locomotives and rolling stock
A selection of original Taff Vale coaches have survived into the present day. Taff Vale Railway Coaches No.220, 153, 145, 52 and 31 are all preserved at the Gwili Railway in west Wales, and are in the care of the Gwili Vintage Carriage group. TVR coach No.73 has also been restored to service on the Swindon and Cricklade Railway.
Coaches No.277, 210 and 112 stand in a private residence. No.203, 48 and 51 are now owned by the National Museums & Galleries of Wales. Only one mineral wagon is known to still exist today, at the Didcot Railway Centre.
Two locomotives are preserved. One is Taff Vale Railway O2 class class 0-6-2T No. 85, built in 1899 at Neilson, Reid & Co., Glasgow. It is currently undergoing overhaul on the Keighley and Worth Valley Railway.
The other is Taff Vale Railway O1 class class No. 28, built in 1897 at Cardiff West Yard Locomotive Works, making it the last surviving Welsh standard-gauge locomotive. It is owned by the National Railway Museum, under the custodianship of the National Museum of Wales and requires a major overhaul.
As of 2013, the cosmetic restoration of No. 28 was to go ahead. The aim was to return the locomotive to original condition.
- Trevithick had experimented with steam engines at Coalbrookdale in 1802.
- Brunel originally chose the broad gauge for the Great Western Railway on the basis that large diameter carriage wheels could be located outside the width of the body, as in stage coaches. The larger diameter wheels would give smoother running at high speed. In fact Brunel abandoned that idea when the rolling stock for the GWR was being produced.

- The Newport, Abergavenny and Hereford Railway amalgamated with others to form the West Midland Railway in 1860, and that company amalgamated with the Great Western Railway in 1863.
- The zigzag was in front of Jones Street, Tonypandy, on the land now occupied by Glan-y-Llyn.
- The junction there was known as "Llantrisant Junction".
- Some authors spell this Bwlffa, but that is a mistake.
- The GWR later opened a station named Nelson & Llancaiach replacing their Llancaiach station.
- The Grouping is popularly supposed to have taken place on 1 January 1923, but in fact the process was phased over more than a year.
- An enthusiasts' special train ran on 15 October 1988.
