SR 4BUF 'Nelson' EMU coach set
TRBufK - Trailer Buffet(final condition)
In 1937 the SR introduced their 12car fully corridor emu trains on the newly electrified Portsmouth line. The name 'Nelson' resulted from the non drivers front window being replaced by destination screen, as corridor door was in centre.
Sets of 4COR and 4RES made up the Portmouth trains.
In 1938 similar trains were introduced on the Mid Sussex line, with buffet car relacing restaurant, in set 4BUF.
Bulleid modified the buffet cars in 1940s, with a brash and contempory interior.
