This publication contains 1,110 abstracts of journal articles and research reports selected by RRIS from current railroad literature and 418 summaries of ongoing research activities in the railroad field. The material covers the entire range of railroading from technology to operations,...
The Transportation Systems Center serves as Systems Manager for the Rail Supporting Technology Program of the Urban Mass Transportation Administration. One task under this program has been to assess the costs of constructing, operating and maintaining three kinds of urban rail systems: light...
This report was prepared as part of the Improved Track Structures Research Program sponsored by the Office of Rail Safety Research of the Federal Railroad Administration. A survey of available wheel/rail load data was conducted (see the Interim Report, D0T-TSC-1051, April, 1976) and noticeable gaps...
A report on the Federal Railroad Administration's activities carried out under the High Speed Ground Transportation (HSGT) Act of 1965 as amended and extended, for the Secretary of Transportation to report annually to the President and the Congress on activities performed under the Act. This report...
This report presents an experimental design for a project to evaluate four techniques for reducing wheel-rail noise on urban rail transit systems: (a) resilient wheels, (b) damped wheels, (c) wheel truing, and (d) rail grinding. The design presents the project questions to be answered: (1) What...
This report summarizes the truck economic research accomplished during Phase I of the Federal Railroad Administration's three-phase Truck Design Optimization Project (TDOP). In this phase: (1) A truck economic methodology was developed with the cooperation of representatives from the railroad...
A first interim report covering the development of the TDOP economic methodology was published by the Federal Railroad Administration in April 1975. It contains the truck investment economic evaluation procedures intended for the use of the railroad industry and their suppliers. The primary...
The Facility for Accelerated Service Testing (FAST) is a track loop located at the DOT Transportation Test Center at Pueblo, Colorado. A train operating around the loop for up to 16 hours per day exposes track and equipment components under test to loads approximately ten times as rapidly as in...
This report has been prepared as part of the Improved Track Structures Research Program sponsored by the Office of Rail Safety Research of the Federal Railroad Administration. The major modes of track degradation have been reviewed to identify the significant wheel/rail loading mechanisms....
Several new capabilities have been added to the DYNALIST II computer program. These include: (1) a component matrix generator that operates as a 3-D finite element modeling program where elements consist of rigid bodies, flexural bodies, wheelsets, suspension elements, and point masses assembled on...
