The British Rail Class 319 is a dual-voltage electric multiple-unit passenger train capable of operating on 25 kV 50 Hz AC from overhead wires or 750 V DC from a third rail. They were built by British Rail Engineering Limited's Holgate Road carriage works for use on north-south cross-London services.
Built in two batches in 1987–88 and 1990, the units were primarily used on the then-new Thameslink service from Bedford to Brighton and various other destinations south of London. The majority of the fleet remained in use on the Thameslink route after its reshaping and privatisation in 1997. Some of the fleet was also used by Connex South Central and latterly Southern on various services operating out of London Victoria, including flagship expresses to Brighton.
Since delivery of new Class 700 rolling stock for Thameslink services began in 2015, the Class 319 units have been redeployed for use in North West England on newly electrified lines but will be replaced in 2021 by Class 323 units cascaded from West Midlands Trains.
Of the 86 Class 319s built, 34 remain in active service, nineteen with Northern Trains and fifteen with West Midlands Trains. As of November 2019, eleven units have been converted to dual mode Class 769s, with another 27 due for conversion. One has been converted to a tri-mode Class 799 which runs on hydrogen and electricity with the 25 kV AC and 750 V DC equipment retained.
Plans for north-south railways across central London go back to the 1940s at least, when there were several proposals in the 1943 County of London Plan which were developed further in a following report in 1946.
The Victoria line, which opened in stages from 1968, had been one of the routes suggested in these plans. Another involved reviving the disused Farringdon to Blackfriars route for passenger trains, and this began to be considered seriously in the 1970s. The British Railways Board then developed plans for what would become Thameslink, and the newly-created business sector of Network SouthEast inherited responsibility for the project in 1986. Services between Bedford, Farringdon, Blackfriars and Brighton began under the Thameslink brand in 1988.
As the Thameslink service was to use a route with 25 kV AC OHLE north of Farringdon and along the branch to Moorgate, and 750 V DC third-rail electrification south of Farringdon, the Class 319 trains were equipped for dual-voltage operation, making them very versatile. They were also the first British Rail units to use modern thyristor control in place of a camshaft and resistor bank.
The body shape of the Class 319 is slightly different from contemporary electric units due to restrictions in the loading gauge in Kings Cross Tunnel, which meant that other dual-voltage units were not suitable. They were also required to have emergency end doors in the cabs, due to the twin single-bore layout of Smithfield tunnel preventing normal train evacuation.
Two sub-classes of Class 319 units, 60 Class 319/0s and 26 Class 319/1s, were originally built. Over the years, the units have been refurbished, creating five sub-classes, of which four still exist.
Class 321 passenger units and Class 325 postal units were developed from the Class 319 design, using similar traction equipment and the same steel body design, with revised cab designs. The 325 units used a Networker style cab design.
The first batch of 60 units, built in 1987 and 1988, was classified as Class 319/0. Units were numbered in the range 319001–060 and had a maximum speed of 100 mph (161 km/h). Each unit consisted of four steel carriages: two outer driving trailers, an intermediate motor with a roof-mounted Stone Faiveley AMBR pantograph and four DC GEC G315BZ traction motors (two per bogie), and an intermediate trailer housing a compressor, motor alternator and two toilets. Seating was standard-class only, in 2+3 layout.
The technical description of the unit formation is DTSO(A)+MSO+TSO+DTSO(B). Individual vehicles were numbered as follows:
- 77291–77381 (odd) and 77431–77457 (odd) — DTSO(A)
- 62891–62936 and 62961–62974 — MSO
- 71772–71817 and 71866–71879 — TSO
- 77290–77380 (even) and 77430–77456 (even) — DTSO(B)
Vehicles were numbered in two ranges, corresponding to units 319001–046 and 319047–060. The gaps in the number series (e.g. 77382–77429) were filled by the Class 442 units, built around the same period.
The DTSO(B) vehicles originally featured a lockable sliding door between the driving cab and the first set of power doors and tip-up longitudinal seating to enable parcels to be carried securely. This facility was rarely used and the sliding door has been removed.
Units 319001-319003 and 319005-319013 are the remaining members of the 319/0 subclass; all others were converted to Class 319/2 or Class 319/4 in the late 1990s. One unit (319004) was scrapped in January 2020.
Built in 1990, this second batch of 26 units was numbered in the range 319161–186. The formation of the second batch of sets was similar to that of the earlier units, with the addition of first-class seating at one end of the train for use on longer-distance Bedford to Brighton services. Like the first batch, standard-class seating was of a 2+3 layout. First-class seating was in 2+2 layout.
Units were formed in the arrangement DTCO+MSO+TSO+DTSO. Individual vehicles were numbered as follows:
- 77459–77497 (odd) and 77971–77983 (odd) — DTCO
- 63043–63062 and 63093–63098 — MSO
- 71929–71948 and 71979–71984 — TSO
- 77458–77496 (even) and 77972–77984 (even) — DTSO
Vehicles were numbered in two ranges, corresponding to units 319161–180 and 319181–186. A more modern Brecknell Willis high speed pantograph was also fitted.
All were converted to Class 319/3 in the late 1990s.
In 1997, seven of the Class 319/0 sets were converted especially for use on Connex South Central express services between London Victoria and Brighton. Work carried out at Railcare Wolverton included new, lower-density seating, a disabled toilet, and a special 'lounge' seating area in the saloon space below the pantograph in the MSO, where stowage for a refreshment trolley and a small serving counter were also fitted.
Units involved were renumbered from 319014–020 to 319214–220. They retain their low-density layout, but the lounge area has been replaced by standard seating since their return to use on Thameslink services.
In the period 1997-99, Thameslink arranged for all of its 319/1 units to be converted at Eastleigh Works for use on the shorter-distance Luton to Sutton/Wimbledon services, then known as 'Thameslink CityMetro'. These units lost their first-class seating and were renumbered into the 319/3 series. They were painted in a navy-blue and yellow livery at this time.
Various refurbishments have taken place since 1999, including:
- Minor refresh by Thameslink including new seat covers between 2003 and 2005
- Relivery and interior refresh by Railcare Wolverton for First Capital Connect completed in 2010
- New passenger information system, new seat covers and an internal and external repaint for units transferring to Northern Rail and similar work for those remaining on Thameslink in the interim, starting in 2014.
Units 319021-060 were refurbished for Thameslink at Railcare Wolverton from 1997-98. Work included the installation of a first-class compartment at one end, in the DTSO(A) vehicle and the removal of some seating in the centre of each vehicle to give 2+2 layout. Cosmetic improvements included new carpets and seat coverings, as well as application of the navy-blue Thameslink livery.
Upon completion, these units were renumbered as 319421-460 and moved on to the Bedford to Brighton service, branded as 'Thameslink Cityflier'.
From 2003 to 2005, during the Thameslink blockade, some minor interior updating took place such as recovering seats with an updated Thameslink moquette. First-class compartments were refurbished with new carpet, retrimmed seats and chrome-plated heater panels, apart from unit 319444, which retained its 1997-designed interior.
A later refresh was unveiled by the then-new operator First Capital Connect on 26 October 2006. Unit 319425 was renamed Transforming Travel for the occasion and showcased the following improvements:
- Emergency brake pressure increased to the +12% G standard, giving an extra 1 Bar brake cylinder pressure in emergency
- Emergency brake 'timeout' period reduced from 2 minutes to 20 seconds
- DC traction motors rewound to improve reliability
- Improved motor control hardware with a new Remote Communications Frame
- New 'easy to clean' flooring
- Retrimmed seats into the First Capital Connect moquette
- Some seats in standard class were removed and vertical luggage stacks installed in their place; a further two seats were removed in the TSO vehicle to allow easier access to the toilet
- Repainted dado side panels and wall ends
- Existing stanchions painted pink
- New stanchions leading from some seats to the overhead luggage rack to provide standing passengers with something to hold on to and more support
- Improved, brighter fluorescent lighting diffusers
The refresh took place at Railcare Wolverton works and also featured both a mechanical overhaul (under the solebar) and a full exterior relivery, again in vinyl. Some Class 319/4 units have had their Stone Faiveley AMBR air and spring pantograph replaced by the more modern Brecknell Willis High Speed air-only pantograph design.
After the withdrawal of the final six Class 319 units from the Thameslink network on 27 August 2017, just over half of the original Class 319 fleet is currently in service, with many currently in storage at Long Marston. 17 units are currently allocated to Northern Trains. West Midlands Trains is the only other operator of the Class 319, with three 319/0, all seven 319/2 and five 319/4 units currently on fleet.
To operate on newly electrified routes in the North West of England, Northern Rail received twenty Class 319/3 units after they were replaced by brand new Class 387 units. The first Northern Rail service to be operated by Class 319s was the Liverpool Lime Street to Manchester Airport via Chat Moss service on 5 March 2015. From 17 May 2015, the Liverpool Lime Street to Wigan North Western via Huyton route followed suit.
The first batch of units which transferred to Northern Rail underwent a light refurbishment at Wolverton Works and were repainted into a dedicated Northern Electrics livery, although all of these units had been repainted into Northern's livery by mid 2018.
Other services now operated by Class 319s include Crewe to Liverpool via Earlestown, Liverpool to Warrington Bank Quay and Liverpool to Wigan North Western and Blackpool North. In April 2016, these units transferred to the then-new franchise operator Arriva Rail North, who have since leased an additional fifteen Class 319s to operate on newly electrified services from Blackpool North, with these commencing in May 2018.
In December 2016, it was announced that Northern's allocation of 319/4s were to be converted to Class 769 Flex bi-mode multiple units by Brush Traction at Loughborough, with the remaining 319/3s due to operate on existing and future electrified services.
In August 2019, it was confirmed that all 319s would leave Northern to be replaced by 17 of the 26 Class 323 units operated by West Midlands Trains. This is expected to occur once new rolling stock is in operation with West Midlands Trains in 2021.
On 1 March 2020, following the collapse of previous operator Arriva Rail North, the Northern 319s transferred to new government-owned operator Northern Trains.
West Midlands Trains
Seven units were transferred to London Midland in 2015 to operate the Watford Junction to St Albans service and some peak West Coast Main Line services out of London Euston. These replaced the seven Class 321 units that transferred to Abellio ScotRail. In April 2017, one of the five Class 319/4 units, 319455, was swapped for 319433, with the latter receiving a light refresh and a repaint before entering service.
In December 2017, West Midlands Trains (a consortium of Abellio, JR East and Mitsui) took over the operation of the West Midlands rail franchise, with the seven Class 319 units initially leased by London Midland transferring to the new operator under the London Northwestern Railway brand.
A week after the start of the new franchise, West Midlands Trains leased additional Class 319 units, which had previously operated with Thameslink. These extra units enabled the company to take their Class 350/1 and 350/3 Desiro units out of service for their planned refurbishment.
All of the Class 319 units operated by West Midlands Trains are scheduled to be replaced by new Class 730 units.
Rail Operations Group/Orion
Orion High Speed Logistics is aiming to launch its first trial service conveying parcels and light freight in April 2021, with the Midlands to Mossend now likely to be the debut flow. The company is to use converted Class 319s for the service and is now planning for a fleet of 19 four-car units – nine Class 319s and 10 Class 769s. Arlington Fleet Services at Eastleigh is modifying the interiors of the units to accommodate roller cages for parcels, with the aim of operating primarily under electric power but with the 769s using their diesel engines to act as tractor units for the 319s on non-electrified stretches. Orion unveiled its first modified 319, No 319373, at Eastleigh in August 2020, and from 18 to 20 January 2021 showcased the unit to potential partners and customers at Maritime Transport’s Birmingham Intermodal Freight Terminal at Birch Coppice. 
With the first units entering service for Thameslink in 1988, Class 319s were a mainstay on the Thameslink network for almost three decades. In early 2015, the first batch of units were withdrawn from the network after being displaced by Class 387 units.
Twenty Class 319/3s transferred to Northern Rail for newly electrified lines in the North West, with the first units entering service in March 2015 after a light refurbishment. A further seven units left the network in 2015, transferring to London Midland to replace their Class 321 units, which had transferred to Abellio ScotRail.
Since the introduction of the new Class 700 units in June 2016, Class 319s departed the network as new trains have entered service. A further batch of twelve units transferred to the North West of England for service with Arriva Rail North, with the remainder being placed into storage at Long Marston. The six remaining Class 319 units were withdrawn from Thameslink service on 27 August 2017, around 30 years after their initial introduction to service.
Since their withdrawal, a number of additional units have been allocated to Northern and West Midlands Trains to boost capacity.
When British Rail was privatised in the mid-1990s, the first 13 units (319001–013) were used for outer-suburban services by Connex South Central, with some temporarily losing their 25 kV AC overhead equipment.
Seven more of the Class 319/0 sets (319014–020) were refurbished and dedicated to express services between London Victoria and Brighton, before later finding work on peak-only London Victoria to Guildford via West Croydon and London Victoria to Horsham via Three Bridges services. The dual-voltage capability was also used to introduce new services linking Rugby and Gatwick Airport via the West Coast and West London Lines in the 1990s.
Successor company Southern continued to operate the fleet and reliveried it into its own colour scheme. It later went on to sublease Class 319/0 units to First Capital Connect for use on the Thameslink route, before eventually releasing the entire fleet.
Units 319008 Cheriton and 319009 Coquelles are notable for two reasons:
- On 10 December 1993, they travelled through the Channel Tunnel from Sandling to Calais-Fréthun and back with a party of invited guests, after the construction consortium TransManche Link (who were responsible for the construction of the Tunnel) had transferred responsibility for operations and management over to Eurotunnel. Their pantographs were modified at Selhurst Depot beforehand to account for the higher OHL height at Cheriton and in the tunnel. For the subsequent "Folkestone 1994" event on 7 May 1994, which saw the first paying members of the public taken into the tunnel by train. On 26 March 1994 units 319008 and 319009 were named Cheriton and Coquelles respectively at Victoria and plaques adorned with the Union Flag and Tricolore were installed on their motor carriages. Cheriton has been transferred to Transport for Wales to be introduced on the Valley Lines after release by Thameslink, whilst Coquelles has been transferred for use with Rail Operations Group.
- On 26 March 1994, they set a record for the shortest London to Brighton journey time, at 37 minutes 57 seconds. This record stood until 2005 when the "Speed Run" event, organised by Southern, using Class 377 units 377 472 and 377 474 set a slightly quicker record of 36 minutes 56 seconds.
Named units are as follows:

- 319448 – Elstree Studios – The Home of British Film and Television Production (nameplates removed)
- 319449 – King's Cross Thameslink (nameplates removed)
- In January 1999 a Connex South Eastern train formed of Class 423 and Class 411 slam door stock passed a signal at danger and collided with a pair of Thameslink Class 319s at Spa Road junction.
- In January 2014 unit 319369 operated by First Capital Connect was involved in a minor accident when the pantograph failed to lower at Farringdon station due to a technical fault. As a result, it struck the roof of Blackfriars station at about 09:55. No-one was injured and the train was later removed.
Conversion to bi-mode
In December 2016, Arriva UK Trains subsidiary Northern and Porterbrook announced a plan to convert eight Class 319/4 electric multiple units to bi-mode units, to allow through working between electrified and non-electrified routes. These units, which were initially marketed as "Class 319 Flex" before being designated as Class 769 under TOPS, will use two diesel powered alternators fitted under each of the driving trailer vehicles, to power the traction motors through the train's existing DC bus.
The modifications, which will be carried out by Brush, will enable units to operate on electrified and non-electrified routes, using both 25 kV AC overhead wires and 750 V DC third rail. Each generator set will consist of a MAN D2876 diesel engine driving an ABB alternator. The first units were expected to enter service with Northern by spring 2018, but were delayed until 2019, and now 2020 with new operator Northern Trains.
