The British Rail Class 319 is an electric multiple unit passenger train built by British Rail Engineering Limited's Holgate Road carriage works for use on north–south cross-London services. These dual-voltage trains are capable of operating on from AC overhead wires or 750V DC from a third rail.
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.
A total of 44 sets were converted to s which is a mixture of Bi-mode multiple units (BMU) and Tri-mode multiple units. Two Class 319s have been converted to a tri-mode Class 799 which runs on hydrogen and electricity with the 25kVAC and 750VDC 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[2] 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 25kV AC OHLE north of Farringdon and along the branch to Moorgate, and 750V DC third-rail electrification south of Farringdon, the Class 319 trains were equipped for dual-voltage operation.They were also the first British Rail units to use modern thyristor control in place of a camshaft and resistor bank.[3]
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,[4] 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.[5] Over the years, the units have been refurbished, creating five sub-classes, of which four still exist.
passenger units and postal units were developed from the Class 319 design,[3] 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 1000NaN0. 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).[6] Individual vehicles were numbered as follows:
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 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.
Unit 319011 is the only remaining member of the 319/0 subclass; all others were converted to Class 319/2 or Class 319/4 in the late 1990s, or Class 768s Class 769s or Class 799s in the 2010s or scrapped.
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:
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 was replaced by standard seating since following 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:
Units 319021-060 were refurbished for Thameslink at Railcare Wolverton from 1997 to 1998. 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:
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.
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. Arlington Fleet Services at Eastleigh Works 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 over non-electrified routes. 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.[7] The first of ten Class 768s was scheduled to enter service in 2021.[8]
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.[9] These replaced the seven units that transferred to Abellio ScotRail.[10] [11] 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.[12]
All of the Class 319 units operated by London Northwestern Railway were withdrawn on 27 November 2023 after being replaced by Class 730 units.[13]
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 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 units, which had transferred to Abellio ScotRail.
Since the introduction of the new 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.[14]
Following their withdrawal, a number of additional units were allocated to the North West and the West Midlands to boost capacity.
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 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.[15] From 17 May 2015, the Liverpool Lime Street to Wigan North Western via Huyton route followed suit.[16]
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 operated by Class 319s included 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 later leased an additional fifteen Class 319s to operate on newly electrified services from, with these commencing in May 2018.
In December 2016, it was announced that some 319 were to be converted to Flex bi-mode multiple units by Brush Traction at Loughborough, and were planned to enter service with Arriva Rail North in 2018.[17]
In August 2019, it was confirmed that all 319s were planned to leave Arriva Rail North to be replaced by 17 of the 26 Class 323 units operated by West Midlands Trains. This was expected to occur once new rolling stock is in operation with West Midlands Trains.[18] However instead the Class 319s were replaced by Class 331 units.
On 1 March 2020, following the collapse of previous operator Arriva Rail North, the Northern 319s transferred to new government-owned operator Northern Trains.
In September 2023 it was reported that Northern Trains planned to withdraw its Class 319 fleet by the end of 2023,[19] later delayed until January 2024.[13]
Northern Trains withdrew its Class 319 fleet on 2 January 2024.[20]
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[21] 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:
Named units were as follows:
See main article: British Rail Class 768, British Rail Class 769 and British Rail Class 799. 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, 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 were 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 consists of a MAN D2876 diesel engine driving an ABB alternator.[29] The first units were expected to enter service with Arriva Rail North by spring 2018,[30] [31] but were delayed until 2019.[32]
In July 2017, five units Class 769s were ordered by the Welsh Government for the Wales & Borders franchise, to enable Class 150 and Class 158 diesel multiple units to be released from service to undergo modifications to comply with PRM regulations, as well as allowing the company to increase its fleet capacity.[33] Transport for Wales held an option for a further four, which they took up in November 2018.[34]
Transport for Wales' allocation of nine Class 769s were converted from five Class 319/0 and four Class 319/4 units, with the former being the ones ordered under Arriva Trains Wales and the latter being the optional extras selected by KeolisAmey Wales. The first unit, 769002, was delivered to Cardiff Canton depot in March 2019.[35] The class 769 first entered service in November 2020.[36]
Transport for Wales Rail withdrew the last of its Class 769 fleet on 19 May 2023.[37]
Other planned operators of the Class 769 included Great Western Railway.[38] Great Western Railway's units were planned to retain their third-rail pickup shoes.
The introduction of the Great Western Railway Tri-mode Class 769s was abandon in December 2023.[39]
In December 2018, Rail Operations Group (ROG) ordered two Class 769s that were in the process of being developed by Brush Traction from redundant Class 319s. However unlike the Class 769s that remained as passenger trains, ROG's Orion High Speed Trains subsidiary intends to operate them as parcel carriers from London Liverpool Street to London Gateway.[40] In February 2020, a further three were ordered to allow services to be introduced the Midlands to Scotland via the West Coast Main Line.[41] > A further five has since been ordered. Originally to be classified as Class 769/5s, they were reclassified as the Class 768 before first was completed.[42] Two Class 319s, 319001 and 319382, have been converted to a Class 799. They will run on hydrogen on non-electrified routes whilst retaining the existing 25 kV AC and 750 V DC equipment for electrified routes.[43]
In 2020 GB Railfreight used a Class 319 in a trial of a parcel delivery service.[44]
