British narrow gauge railways
There were more than a thousand British narrow gauge railways ranging from large, historically significant common carriers to small, short-lived industrial railways. Many notable events in British railway history happened on narrow gauge railways including the first use of steam locomotives, the first public railway and the first preserved railway.
Early railways: before 1865 
The earliest narrow gauge railways were crude wooden trackways used in coal mines to guide wooden tubs. Because of the restricted loading gauge of the tunnels and the need for the tubs to be small enough to be pushed by one man, these railways were almost all narrow gauge. These underground lines often had short above ground sections as well.
After the start of the Industrial Revolution it became possible to create railways with iron tracks and wheels, which reduced the friction involved in moving wagons and made longer horse-hauled trains possible. These could move more material over longer distances, allowing the construction of railways from mines and quarries to transshipment points on rivers, canals and the coast. The earliest narrow gauge railways that were more than simply internal mine or quarry systems were all horse drawn industrial railways of this sort. Prominent examples include the 3 ft 6 in (1,067 mm) gauge Little Eaton Gangway of 1793, the 3 ft 4 3⁄4 in (1,035 mm) gauge Lake Lock Rail Road of 1796, the 2 ft (610 mm) gauge Llandegai Tramway of 1798 and the 4 ft 2 in (1,270 mm) gauge Surrey Iron Railway of 1803. The Surrey Iron Railway was the world's first public railway.
Meanwhile, the development of the stationary steam engine was proceeding to the point where early steam locomotives were being proposed. In 1804, Richard Trevithick demonstrated the first locomotive-hauled railway in the world: the 4 ft (1,219 mm) gauge Penydarren Tramway in south Wales. Although this first use of locomotives was a limited and short-lived experiment, in 1812, the 4 ft 1 in (1,245 mm) gauge Middleton Railway in Leeds became the first in the world to make commercial use of steam haulage.
Steam technology developed rapidly in the early 19th century, allowing smaller locomotives to haul more goods. The horse-drawn Ffestiniog Railway opened in 1836 to connect the slate quarries at Blaenau Ffestiniog with the coastal port of Porthmadog. The traffic on the line quickly grew to the point where the horses could no longer haul the empty slate wagons back to the quarries quickly enough to meet demand. In 1863, steam locomotives were introduced on the 1 ft 11 1⁄2 in (597 mm) gauge railway, with passenger services following in 1865. This was the first steam operated railway providing both freight and passenger services on such a small gauge and it proved the model for the introduction of narrow gauge railways across the world.
In 1846, the British Parliament passed the Gauges Act that established 4 ft 8 1⁄2 in (1,435 mm) as the standard gauge for Britain. After the Gauges Act, most of the railway track laid in Great Britain was to standard gauge. However many minor railways, both public and industrial, were built to narrower gauges. These lines either followed local traditions or were built in locations where the smaller size of the railway proved more economical or was simply necessary due to physical limitations such as bridges and tunnels.
The boom years: 1865–1900 
The success of the Ffestiniog Railway triggered a boom in the construction of narrow gauge railways, not just in Britain but around the world. In the United Kingdom, the centre of narrow gauge construction was North Wales. The mountains of the north held large quantities of slate and their narrow valleys and steep hillsides meant that the smaller narrow gauge railways were cost effective. The major slate mining regions at Bethesda, Llanberis, Blaenau Ffestiniog and Corris all developed multiple railways to serve the quarries. Some of these lines, like the Ffestiniog Railway, the Corris Railway and the Talyllyn Railway were common carriers, while others like the Penrhyn Quarry Railway and the Padarn Railway were purely industrial lines.
Outside Wales, other industries started to use narrow gauge railways to move freight, notably ironstone, limestone, china clay, brick clay and metals. Many common carrier lines were built: all of the railways on the Isle of Man were narrow gauge - mostly 3 ft (914 mm) gauge. A number of railways were built to connect standard gauge railways with smaller towns, including the Southwold Railway, the Wolverton and Stony Stratford Tramway and the famous Lynton and Barnstaple Railway in Devon. These lines allowed communities that did not merit a full railway service to connect to the mainline network at low cost.
The 1880s were the high point of British narrow gauge railways as traffic on many of these lines reached its peak volume and new lines were built across the country.
There were many narrow gauge lines, as the 1904 Railway Clearing House Railway Atlas shows:
|Southwold Railway||3 ft (914 mm)|
|Croesor Tramway||2 ft (610 mm)|
|Ffestiniog Railway||1 ft 11 1⁄2 in (597 mm)|
|Welsh Highland Railway|
|Talyllyn Railway||2 ft 3 in (686 mm)|
|Welshpool & Llanfair Railway||2 ft 6 in (762 mm)|
|Vale of Rheidol Railway||1 ft 11 1⁄2 in (597 mm)|
|Lynton and Barnstaple Railway|
|East Cornwall Mineral Railway||3 ft 6 in (1,067 mm)
later converted to
4 ft 8 1⁄2 in (1,435 mm) standard gauge
Decline of the narrow gauge: 1900–1950 
In 1896, the Light Railways Act was passed which allowed the construction of railways to less stringent standards than had previously been allowed. This led to a short resurgence in the building of narrow gauge railways, especially in rural locations. In Wales, the Welshpool and Llanfair Light Railway was built to serve farming communities; in England the Leek and Manifold Valley Light Railway served similar purposes in the Derbyshire Dales.
However, rail traffic was declining and the invention of the practical motor car at the turn of the 20th century marked the beginning of the decline of public narrow gauge lines in Britain. Most of these railways were built to serve marginal traffic that would not support a larger line. As road competition increased, many existing lines fell into decline and few new railways were built.
The First World War saw a brief resurgence of the narrow gauge as surplus equipment from the War Department Light Railways (WDLR) became available. Several industrial railways were built using second hand WDLR equipment, notably the Leighton Buzzard Light Railway. Other lines such as the Glyn Valley Tramway and the Snailbeach District Railways were able to replace ageing locomotives relatively cheaply and continue to operate on shoestring budgets. Even the famed Ffestiniog Railway acquired a Baldwin locomotive to shore up the fleet working the Welsh Highland Railway which it now owned.
The last commercial carrier, narrow gauge line in Britain was the Ashover Light Railway, opened in 1925 using surplus war equipment. This was the epitome of cheaply constructed light railways and was one of several minor railways owned by Colonel Stephens.
Meanwhile, the use of narrow gauge railways in industry continued to flourish. Many small railways were built to serve sand and gravel pits, cement works and the peat and timber extraction industries. Again, these often used rolling stock brought second hand from the WDLR.
However, the continued development of road transport and the economic crises of the 1930s saw a slow decline in the use of narrow gauge railways across the country. The advent of the Second World War pushed many struggling enterprises into bankruptcy as labour and materials were diverted to the war effort. During and immediately after the war, the majority of the remaining lines closed: between 1946 and 1950 the Ffestiniog, Corris, Talyllyn, Ashover Light, Rye and Camber and Eaton Hall railways all closed. Many industrial lines did not survive the war years.
The narrow gauge after 1950 
The use of narrow gauge railways in Britain declined throughout the first half of the 20th century. This decline accelerated after the Second World War as improved road transport displaced railways in industry and for passenger service.
In 1951 however, a group of railway enthusiasts, alarmed at the loss of this part of British industrial heritage, stepped in to save the failing Talyllyn Railway. This became the first railway to be run entirely by volunteers and sparked a movement to preserve many railways, both narrow and standard gauge as tourist attractions. Since then many lines have been preserved as working museums, and new narrow gauge railways are being constructed for the tourist industry.
In the 21st century a very few industrial and common carrier lines survive. Notable amongst the latter are the Glasgow Subway, an underground metro line that operates on a 4 ft (1,219 mm) gauge, and the Manx Electric Railway on the Isle of Man.
Significant lines 
Amongst the most well-known narrow gauge lines in Britain are the Ffestiniog - now the oldest independent railway company in the world - the Vale of Rheidol, and the Welshpool & Llanfair in Wales, and the Lynton & Barnstaple in England. Unique amongst British railways is the rack-and-pinion Snowdon Mountain Railway which climbs to just below the summit of Wales' highest peak.
The 3 ft (914 mm) gauge Isle of Man Steam Railway operates as a tourist attraction. Also on the Isle of Man is the 3 ft 6 in (1,067 mm) gauge Snaefell Mountain Railway which climbs the island's main peak and is the sole operating Fell system railway in the world.
The narrow gauge railways of Britain and the Isle of Man 
Public railways 
These are narrow-gauge railways that ran public passenger trains for a significant portion of their existence. In 1951 the Talyllyn Railway was the first railway in the world to be taken over and preserved by volunteers. This was the birth of the heritage railway movement, which has flourished in Britain and around the world in the years since. As a result, many of these lines passed from being common carriers and were preserved as heritage railways after their demise. Where this has happened their heritage existence is included as a second row.

Private railways 
These are private lines or collections owned by individuals or small groups and generally not open to the public.
Industrial railways 
Great Britain was home to many industrial narrow gauge railways, ranging from temporary hand-powered lines a few yards long to significant locomotive-worked complexes of lines that served substantial industrial concerns.
Military railways 
Many British military establishments and former UK Government-owned explosives sites used narrow gauge railways. These locations were often subject to the Official Secrets Act and other government restrictions, so many of them are less well documented.
The industrial use of narrow-gauge railways was quite extensive amongst the various military and civilian explosive factories, for example ICI Nobel's works at Ardeer and the Agency Explosive Factories run by ICI Nobel in the Second World War. To give an example, the Ministry of Supply (MOS) Factory Dalbeattie used 2 ft 6 in (762 mm) gauge with a variety of bogie trucks mostly pushed by teams of three to six women. Stores, explosives, chemicals, rubbish and sewage, were all transported on this narrow-gauge system, which used at least 8 miles (13 km) of track.
