Class 508 unit no. 508302 (formerly 508135) enters from the north.
The 508s first appeared as 4-car units on the South Western division of Southern Region.
They were all transferred to Merseyside as part of the electrification scheme, but not before each unit had left one intermediate trailer behind.
The trailers were subsequently formed into the first batch of Class 455s, the 455/7s, which were built as 3-car units. Photo by Mark Ziemba, scan by Fuji #zedbedman@netscape.net
