Special baseplate developed to measure vertical load on track; with baseplates on every sleeper in vicinity of rail joints, maximum vertical loads on running-on ends of rails were obtained at several places; from wheels having identical loads and carrying unsprung weights, results obtained at different sites varied considerably, and it was established that stiffness of track bed plays important part; it is concluded that any advantage to be gained on track from fully-sprung electric motors instead of axle-hung motors is negligible, and that magnitude of maximum load is primarily influenced by speed and stiffness of track bed rather than by amount of unsprung weight carried by wheel.
