APT-E curving tests on the Old Dalby test track during February 1974 (TN-DA-38)

This experiment had two main aims, firstly to measure the quasi-static lateral curving forces in an experimental Advanced Passenger Train E1 power bogie and E1T trailer bogie, and secondly to ascertain the dynamic lateral forces on the track particularly on Upper Broughton curve. Y forces of 0-30Hz bandwidth are used...
