A Driving Brake Standard Open (DBSO) is a type of railway carriage in Great Britain, converted to operate as a control car; this is not to be confused with DVTs, such as those in InterCity 225 sets. Fourteen such vehicles, numbered 9701 to 9714, were converted from Mark 2FBrake Standard Open (standard class coaches with brake van) carriages. Modifications included adding a driving cab and TDM equipment to allow a locomotive to be driven remotely. Using a system known as push–pull, the driver in the DBSO can drive the locomotive, even though it is at the rear of the train.
The vehicles were converted in two batches. Numbers 9701–9710 were converted in 1979 for use on the newly introduced Glasgow–EdinburghInterCity ScotRailpush–pull service with specially modified Class 47/7 locomotives. A further four, 9711–9714, were converted in 1985/86. The fourteenth was a replacement for no. 9706, which was derailed and damaged beyond repair in the Polmont rail crash after it hit a cow.[1]
When first introduced, the DBSO fleet had half-cabs and retained their end gangways. They were later rebuilt to have full-width cabs, with the removal of the end gangways.[citation needed]
As part of the privatisation of British Rail, the London–Norwich route became part of the Anglia Railways franchise. From 1997 onwards, a new livery of turquoise with a white stripe was introduced onto all Anglia stock. However, rake AR01, containing DBSO 9710 retained its old InterCity livery. On the Anglia services they were originally attached to the first class coaches but this was changed and they were attached to the standard class coaches as the seating in the DBSO was standard class.
In April 2004, the Anglia franchise became part of the new One franchise. The thirteen surviving DBSOs were still in service, although they were gradually replaced by Driving Van Trailers (cascaded from Virgin Trains). One DBSO, no. 9710, had the new one Anglia livery applied by means of adhesive vinyls, whilst retaining the InterCity livery underneath.
However, many of the new Mark 3 sets being received by Anglia were not originally accompanied by DVTs. For this reason a small number of DBSOs were retained until enough DVTs had been received. The last DBSOs were withdrawn from mainline service in December 2006. DBSO 9713 was preserved for further use on the Mid-Norfolk Railway, although this was later sold to Direct Rail Services and scrapped following component recovery.
Network Rail DBSO 9708 at Stafford station on a test train 18 November 2018
In February 2007, Network Rail took delivery of five DBSOs, nos. 9701, 9702, 9703, 9708 and 9714. These have been converted to allow test-trains to run in push–pull mode, therefore eliminating the need to operate two locomotives (one at each end of the train).[3] Three of these (9701, 9708 and 9714) were subsequently fitted with a 60 kVA diesel generator to provide power for onboard systems while in operation.[4]
Ex Anglia MK2 driving trailer 9712 was sold to Northern Ireland Railways for use on the ex Gatwick set to convert it to push–pull operation using 111 class locomotives. It is registered as 8918 on NIR. The vehicle was delivered to Belfast on 26 June 2009, almost 14 months late on its contracted delivery date. The ex-Gatwick coaches were stopped on 19 June (before it was delivered) and have now been withdrawn.
In September 2017, DBSO 9711 was acquired by Crewe Diesel Preservation Group for preservation alongside Class 47/7 locomotive 47712 and moved to Crewe Heritage Centre.
In 2022, Direct Rail Services offered their five DBSO vehicles for sale. Locomotive Services Limited acquired 9704 and 9707, Eastern Rail Services acquired 9709 and 9710 and 9705 was purchased by Europhoenix Limited.[7]
On 18 October 2022, Locomotive Services Group revealed that 9707 had been repainted back into its 1980s ScotRail livery; it is expected that it will operate its first charter train in early 2023, as part of a six-coach set, with 47712 Lady Diana Spencer.[8]
InterCity was introduced by British Rail in 1966 as a brand-name for its long-haul express passenger services.
A Driving Van Trailer (DVT) is a British purpose-built control car railway vehicle that allows the driver to operate with a locomotive in push-pull formation from the opposite end of a train. A key benefit of operating trains with DVTs is the requirement for fewer locomotives; for example, a second locomotive would otherwise have to join at the other end of the train after arrival at terminal stations to lead the train's onward journey.
The British Rail Class 47 or Brush Type 4 is a class of diesel-electric locomotive that was developed in the 1960s by Brush Traction. A total of 512 Class 47s were built at Brush's Falcon Works in Loughborough and at British Railways' Crewe Works between 1962 and 1968, which made them the most numerous class of British mainline diesel locomotive.
The British Rail Class 86 is a class of electric locomotives built during the 1960s. Developed as a 'standard' electric locomotive from earlier prototype models, one hundred of these locomotives were built from 1965 to 1966 to haul trains on the then newly electrified West Coast Main Line (WCML) from London Euston to Birmingham, Crewe, Liverpool, Manchester and later Glasgow and Preston. Introduction of the class enabled the replacement of many steam locomotives, which were finally withdrawn by British Rail in 1968.
The British Rail Class 488 are unpowered trailer sets, converted from Mark 2F coaches for the Gatwick Express service from London Victoria to Gatwick Airport.
The Mark 2 family of railway carriages are British Rail's second design of carriages. They were built by British Rail workshops between 1964 and 1975. They were of steel construction.
The British Rail Mark 3 is a type of passenger carriage developed in response to growing competition from airlines and the car in the 1970s. A variant of the Mark 3 became the rolling stock for the High Speed Train (HST).
A wide variety of hauled coaches have been used on the railways of Ireland. This page lists all those since 1945.
A propelling control vehicle (PCV) is a type of British railway carriage for carrying mail. They were converted from Class 307 driving trailers and have a cab at one end which allows slow-speed movement control. PCVs are unpowered but the controls allow mail trains to be reversed at low speed, using the power of the locomotive at the other end of the train. Similar BR Class 91 driving van trailer (DVT) used on the ECML differ by being fully equipped for high-speed train control.
The British Rail Class 43 (HST) is the TOPS classification used for the InterCity 125 High Speed Train (formerly Classes 253 and 254) diesel-electric power cars, built by British Rail Engineering Limited from 1975 to 1982, and in service in the UK since 1976.
The British Rail Class 90 is a type of electric locomotive. They were built for mixed-traffic duties, operating from 25 kV AC overhead lines and producing 5,000 bhp (3,700 kW). They weigh 84.5tonnes and can typically achieve a top speed of 110 mph (177 km/h).
The Glasgow–Edinburgh via Falkirk line is a mainline railway line linking Glasgow and Edinburgh via Falkirk in Scotland. It is the principal route out of the five rail links between Scotland's two biggest cities, hosting the flagship "Shuttle" service between Glasgow Queen Street and Edinburgh Waverley. A typical service calls at Glasgow Queen Street, Croy, Falkirk High, Haymarket and Edinburgh or Glasgow Queen Street, Falkirk High, Polmont, Linlithgow, Haymarket and Edinburgh.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
The Scottish Region (ScR) was one of the six regions created on British Railways (BR) and consisted of ex-London, Midland and Scottish Railway (LMS) and ex-London and North Eastern Railway (LNER) lines in Scotland. It existed from the creation of BR in 1948, and was renamed to ScotRail in the mid-1980s.
The Polmont rail accident, also known as the Polmont rail disaster, occurred on 30July 1984 to the west of Polmont, near Falkirk, in Scotland. A westbound push-pull express train travelling from Edinburgh to Glasgow struck a cow which had gained access to the track through a damaged fence from a field near Polmont railway station, causing all six carriages and the locomotive of the train to derail. 13people were killed and 61others were injured, 17 of them seriously. The accident led to a debate about the safety of push-pull trains on British Rail.
A control car, cab car, control trailer, or driving trailer is a non-powered rail vehicle from which a train can be operated. As dedicated vehicles or regular passenger cars, they have one or two driver compartments with all the controls and gauges required to remotely operate the locomotive, including exterior locomotive equipment such as horns, bells, ploughs, and lights. They also have communications and safety systems such as GSM-R or European Train Control System (ETCS). Control cars enable push-pull operation when located on the end of a train opposite its locomotive by allowing the train to reverse direction at a terminus without moving the locomotive or turning the train around.
A First Open or FO, is a type of railway carriage used by British Rail and subsequent operators since privatisation. They were first produced as British Railways Mark 1, and subsequently Mark 2, Mark 3, and Mark 4 variants were produced. This type of carriage is an "open coach" because of the arrangement of the seats inside – other types of carriage may be corridor based variants (FK) or have a brake compartment.
The Córas Iompair Éireann/Iarnród Éireann 071 Class or Northern Ireland Railways 110 Class or Serbian Railways JŽ series 666 is a General Motors Electro-Motive Division EMD JT22CW series diesel-electric locomotive used in the Republic of Ireland, Northern Ireland and Serbia.
The Class 68 is a type of mainline mixed traffic diesel-electric locomotive manufactured by Stadler Rail for Direct Rail Services (DRS) in the United Kingdom. The design is derived from the Stadler Eurolight, and Stadler's product name for this variant is the UKLight.
