PROPULSION OF TRAINS ON SHARP CURVES

A model to simulate the forces resulting in overturning and flange-climbing with propelled trains on sharp curves led to a series of tests arranged on a sharp curve at Dover. An axlebox lateral-force gear was used to measure the elements of the flange force present at the axleboxes, and load measuring baseplates were fixed between the outer rail and the sleepers to measure the vertical loads imposed by the wheels as well as the lateral loads. The latter are equal to the flang forces, less the lateral tread friction at the outer rail. The results of these tests showed that the increased lateral force when propelling exceeded considerably the value attributable to the propulsive effort and the angle between the coaches.
