RDB975634 and RDB975635


'POP'

This test train originally consisted of two mock Power cars (PC3 – RDB975634 and PC4 – RDB975635) with nothing (O) in between hence the nickname 'POP', it was used from September 1971 as a test bed proving the suspension, tilting and braking systems.

Later the POP train was modified with a prototype APT-P vehicle (Laboratory 8 - 'PILOT' RDB975636) being built and formed between the original POP vehicles, which were re-mounted on revised bogies and given body cladding.

The three vehicle set then performed bogie and ride research work, mainly on the West Coast Main Line. All three POP-II Train vehicles were scrapped during October 1985 by Ward Ferrous Metals Ltd., on site of the Railway Technical Centre in Derby.
