Ballast Degradation Characterized through Triaxial Testing

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 for Evaluating the Costs and Benefits of Railroad Electrification, Volume I - Model Description and Application

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...

User's Manual for Program CONWHEEL (CONformal WHEEL-rail Contact Stress Problems): Technical Report No.10

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...

User's Guide for a Computerized Track Maintenance Simulation Cost Methodology

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...

Truck Design Optimization Project (TDOP) Phase II: Final Report

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...

Track Component Property Tests Volume II: Rails, Ties, Joint Bars and Fasteners

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:...

The Second International Heavy Haul Railway Conference: Pre-Conference Proceedings

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.
