British Rail Class 505
introduced in 1931, jointly with the London, Midland and Scottish Railway, in the Manchester area
British Railways Class 505 were 1,500 V DC electric multiple units (EMUs) introduced in 1931 by the Manchester, South Junction and Altrincham Railway (MSJAR). Although assigned to TOPS Class 505 by British Railways, these units were withdrawn before the TOPS numbering system came into common use for multiple units, and the Class 505 designation is very rarely used.
