POP Train as seen in British Transport Film 'E for Experimental'.
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 Train vehicles were scrapped during October 1985 by Ward Ferrous Metals Ltd., on site of the Railway Technical Centre in Derby.
