    Mercury - a former Southern Region passenger coach, modified to take laboratory equipment, a 25KVA diesel generator and catering facilities for the technical staff.

    Used in the transponder research investigating methods of track-train communication, leading to the development of the Control APT (C-APT) System.

    During 1974 the test coach was hitched to any convenient train operating between London and Birmingham, travelling over this route three times a day, it allowed the initial transponders performance to be analysed.
