Proposals for fitting electro-mechanical tilt actuators to an APT-P vehicle (TM-DOS-103)

The R & D Division started work on the development of an electro-mechanical alternative to the currently used servohydraulic tilt system in 1979, and a pair of prototype actuators were fitted to one of the POP train vehicles (PC3) and tested in 1980 (Refs 1 & 2). Some 8000 miles...
