    This test train originally consisted of two mock Power cars (PC3 - RDB975634 and PC4 - RDB975635) with nothing (0) 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 P-O-P train was modified with an APT-P vehicle (Laboratory 8 - 'PILOT' RDB975636) being built and formed between the original P-O-P 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.

    Lab 8 'Pilot' was the very first APT-P Trailer Car, and was built at Derby C&W in the middle 70s. It remained unpainted in the RTC Yard for some time, mounted on slave bogies, before being fully fitted out during 1978.
