STRESS MEASUREMENTS IN SEVEN DESIGNS OF TIE PLATES FOR 112-LB RE RAIL ON THE ILLINOIS CENTRAL SYSTEM

Investigations of tie plate design are made in a test installation of tie plates for 112-lb rail on the Illinois Central System in October, 1944, and for 131-lb rail on the Southern Railway System in November, 1944. Topics discussed include stress measurements in seven designs of tie plates for 112-lb RE rail on the Illinois Central System, relative vertical movement and rocking of tie plates on the ties under traffic, measurement of the magnitude and eccentricity of tie plate loads, service test data for seven designs of tie plates in 112-lb and 131-lb RE rail, and supplemental measurements of mechanical wear of ties. Periodic measurements are made. It is concluded that tie plate stress increases as the plate thickness is reduced. Test results for the flat seat and beveled crown tie plates are more favorable than those for the rolled circular crown or pressed camber plates.
