Transportation Technology Center, Inc. (TTCI) has supported the development of a large-scale triaxial test device for testing ballast size aggregate materials at the University of Illinois at Urbana-Champaign (UIUC). This new test equipment uses monotonic compression and repeated load testing to...
A model has been developed to evaluate the economic benefits of large scale railroad electrification. Site specific factors which have a major impact on the rate-of-returns are included as input data, thus providing a procedure for comparing the economics of individual routes in a uniform and...
CONWHEEL (CONformal WHEEL-rail contact stress problems) is an all FORTRAN computer program for the solution of normal contact stresses between two closely conforming (possibly nonHertzian) smooth elastic bodies. It can be used to determine: the boundary of the interface contact region; pressure...
This User s Guide describes the simulation cost modeling technique developed for costing of maintenance operations or track and its component structures. The procedure discussed provides for separate maintenance cost entries to be associated with definable track substructures such as rail, cross...
The overall objectives of the TDOP Phase II are to provide technological and economic bases for assessing freight car truck performance and design, and to generate uniform testing and performance guidelines for truck/carbody systems. This report summarizes the approaches employed in this study...
This report describes the test procedures and results from a series of tests on the physical properties of concrete ties, rails, joint bars and rail fasteners, conducted at the Association of American Railroad's Track Research Laboratory in Chicago, Illinois. The properties investigated were:...
This document compiles the papers to be presented at the Second International Heavy Haul Railway Conference from September 25-30, 1980, in Colorado Springs, CO.
[From the Introduction] The 1980 Summary of Accidents Investigated by the Federal Railroad Administration (FRA) includes 130 railroad accidents. This summary provides the following information: the railroad(s) involved, the location and time of the accident, the type of railroad accident, the...
A series of tests were performed at the Factory Mutual Test Center 1) to obtain information on the performance of various extinguishing agents used with hand-held fire extinguishers to control fire involving a Midel, a transformer fluid for replacement of Askarel, and 2) to compare the results with...
