Under the British Rail TOPS computer system, Class 405 was allocated to surviving examples of the Southern Railway 4-Sub Class electric multiple units built between 1941 and 1951. Details of the origins and history of that class are found in the SR Class 4Sub article.

History[]

179 out of the 184 new units constructed between 1946 and 1951 were still surviving at the introduction of the TOPS computer system in the early 1970s,^[1] but were expected to have limited working lives. All surviving units were allocated to Class 405, but divided into two sub-classes. Sub-class 405/1 included the former Southern Railway sets numbered between 4112 and 4387, and sub-class 405/2 included the former British Railways sets built after 1949 and numbered between 4601 and 4754.^[2] All had been withdrawn by 1983.
