Instrumentation for APT'E' lateral dynamics tests at Old Dalby 6/1/75 -9/1/75 (IM-IS-311)

The purpose of the tests was to determine the vertical and lateral forces acting on the EI/2 bogie whilst running the train at constant speeds up to max of 100 M.P.H. Transducers were mounted around the EI/2 bogie to measure the velocity, displacement and acceleration quantities acting in a...
