The British Rail Class 92 is a series of dual-system electric locomotives that British Rail (BR) procured for use between Great Britain and France through the Eurotunnel . Nine of the total of 46 machines were given to the French state railway SNCF , which they designated as the CC 92000 series (road numbers 92006, 010, 014, 018, 023, 028, 033, 038 and 043). In addition to being used in cross-border freight transport , the locomotives should also run before “Nightstar” night trains between northern Great Britain and mainland Europe. For these assignments, the European Passenger Services (EPS) company received seven Class 92 (92020, 021, 032, 040, 044, 045 and 046). All of the locomotives were given the names of famous European writers or composers .
History and description

The locomotives were built by a consortium of the manufacturers Brush Traction and Asea Brown Boveri (ABB). They were designed according to the British clearance profile for open use in both countries . At a length of 21.36 m, they are only 2.64 m wide, which gives them a slim appearance.
The locomotive boxes were largely taken over from the Class 60 diesel series . In order to meet the safety standards in the Channel Tunnel and the European norms, however, they were given modified and reinforced fronts, which were kept yellow in accordance with British regulations. They rest on two six-axle bogies . Each axis is driven by a three-phase asynchronous motor. There is one converter per bogie , which is controlled by GTO thyristors and the ABB MICAS-S2 control system. Most of the electrical systems are redundant in order to reduce the risk of a locomotive failure in the tunnel.
The power supply of the machines with alternating current of 25 kV and 50 Hz is provided by a single-arm pantograph from an overhead line . The locomotives have 12 sliding contacts on the side for operation with a direct voltage of 750 V, which is obtained from busbars . They are equipped with recuperation brakes, have double traction and are suitable for push-pull train operation. The color of the locomotive bodies originally corresponded to the Railfreight Livrée (two shades of gray), the dark blue of the roof that of the Eurostar trains . Three raised circles on the long sides symbolized the Eurotunnel.
In April 1993, the first machine left the Brush factory in Loughborough , England , and the last was delivered in 1996. All locomotives, including those of the SNCF, were based in the British depot Crewe . The planned use of the EPS locomotives in front of "Nightstar" trains was not implemented, until 2015 all Class 92s ran exclusively in front of freight trains .
On November 21, 1997, the 92003 “Beethoven” was the last Class 92 on the road for British Rail. After the state railway company was broken up, the Class 92 belonging to its Railfreight Distribution freight division went to the English, Welsh & Scottish Railway (EWS), which has been part of Deutsche Bahn AG since November 2007 . The Euro Star International , owner of EPS, offered in 2000 to the non-down for use on night trains machines for sale, but found no takers. In 2007, the Eurotunnel freight transport division Europorte Channel bought five of these locomotives for use in front of freight trains between the two tunnel terminals Dollands Moor and Fréthun . The SNCF locomotives followed the same route in 2011, six of which are now carrying the Caledonian Sleeper night trains . All 16 Class 92 from Europorte went into the pool of GB Railfreight .
For the High Speed 1 route between London and the Eurotunnel, the Class 92 was equipped with the Transmission Voie-Machine (TVM) signaling system from 2011 ; they are now certified for the entire UK AC grid. On March 31, 2015, a Class 92 from GB Railfreight pulled the Caledonian Sleeper from London's Euston Station to Scotland for the first time .
In summer 2018, the former SNCF locomotives 92010, 014, 018, 023, 033 and 038 were in service with the Caledonian Sleeper between London and Edinburgh and Glasgow . She and the 92006 had been painted in Caledonian Blue for these missions. Nine Class 92s ran in Romania for DB Cargo Romania , and four more for DB Cargo Bulgaria in Bulgaria . In the same year, DB Cargo Romania sold its Class 92 to the Russian company Locotech, which rented four of them (472 001, 003, 004 and 005) to Transagent Rail in Croatia .
