23-209 SWR Class 455 No. 5859 departing from Surbiton
Taken 21/04/23; According to Wikipedia the Class 455 "... was originally to be classified as the Class 510, at which point they were planned as a 750 V DC version of the Class 317. However, as the chopper control system at the time was not considered robust enough for the electrically rougher third rail Southern Region, they were fitted with second-hand camshaft control systems and thus classified as the 455 class.[
A total of 505 carriages were built by British Rail Engineering Limited's Holgate Road carriage works and together with 43 existing trailers from Class 508s, formed 137 four-car sets. The 455s allowed the Class 405 and Class 415 to be withdrawn, as well as allowing the Class 508s to be transferred to the Merseyside network for which they were originally intended. They also allowed other stock to be cascaded to the North London and Oxted lines.
There were three batches of Class 455s, all consisting of four cars: driving trailer vehicles at each end, an intermediate trailer vehicle and an intermediate motorised vehicle (powered by four EE507-20J of 185 kW carried on the bogies of the MSO vehicle, some recovered from Class 405s), all originally built to the standard class 3+2 seating arrangement with 316 seats. Technically, they are formed DTSO+MSO+TSO+DTSO.[2] They have the same bodyshell as the Class 317 and Class 318, but as they were designed for inner suburban services they do not feature first class seating, air conditioning or toilet facilities and are restricted to 75 mph (121 km/h).[3] Like the Class 317/318, as well as the diesel Class 150, they are based on the British Rail Mark 3, with a steel construction, unlike the earlier PEP based Class 313, Class 314, Class 315, Class 507 and Class 508, which had an aluminium alloy body"
