FREIGHT CAR TRUCK ROAD SERVICE TESTS--SERIES A, B & C

Review of several U.S. railroad environmental service tests for freight car truck information. Three series of road service tests develop instrumentation practices and program to obtain reliable, complete magnetic tape recorded information as to forces and/or strains on car truck components. "A" test primarily for development of instrumentation; also gaining information on 70 ton car trucks. "B" and "C" test series obtain variety of information on 100 ton hopper car truck in severe service. Recounts conditions and areas of test, analysis of data to be separate report.
