British Rail Classes 371, 381 and 471
From Wikipedia, the free encyclopedia
Class 371, Class 381 and Class 471 were proposed electric multiple unit classes from the Networker family intended to operate services in the south-east of England.[1]

[edit] Class 371 and 381
Classes 371 and 381 were intended as the so-called "Universal Networker", a dual voltage train capable of operating using both 25kV AC from overhead wire and 750V DC from third rail. It was planned that Class 371 would be used on the enhanced Thameslink 2000 services while Class 381 would be utilised on various long-distance routes across the Network SouthEast sector, including Kent Coast services from Victoria and Charing Cross, Great Northern services from Kings Cross and LTS services from Fenchurch Street. In the event, British Rail's financial limitations led to the proposal being cancelled.[2] An artist's impression of the Class 371 can be seen here.
[edit] Class 471
Class 471 was the proposed "Main Line Networker" intended for long distance services on the Kent Coast routes of Network SouthEast. Intended as four car units, the Class 471 was to have featured an end gangway to allow passage between two connected units, with seating in 2+2 and 2+3 arrangements. The mock-up unveiled in August 1991 bore a resemblance to the Class 442 "Wessex Express" units operating to the South-West, but featured sliding doors. The Class 471 project stalled due to British Rail's limited finances; entry into service was due by 1993, and by 1992 there had still been no major work done, blamed on a lack of government investment.[3] An image of the Class 471 mock-up can be seen here.
[edit] Alternative
The cancellation of the Class 371, 381 and 471 led to an alternative proposal. This involved the conversion of a batch of Class 465 DC units into Class 365 dual voltage units, at the same time converting them for long distance usage. A total of 40 units were built, with 24 for the Great Northern routes from Kings Cross and 16 for Kent Coast routes.
The Class 319 is the primary dual voltage commuter unit operating over the Thameslink route, while the Electrostar series is utilised over several long distance routes in the South-East. Both the Class 375 and Class 377 Electrostars have dual voltage sub-classes. The entire Class 365 fleet is now used on the Great Northern routes.
