    Always good to see pictures of departmentals that were scrapped long ago - this one being taken before my railway interest even started!

    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.
