Measurements of Rail/Tie Deflections and Fastener Clip Strains at the Facility for Accelerated Service Testing

Measurements of rail-to-tie deflections and fastener clip strain were made on both concrete and wood tie track at the Facility for Accelerated Service Testing (FAST) in October 1980. These measurements were made to provide a data base for duplicating, if possible, these deflections and strains in a...

Massachusetts Bay Transportation Authority No. 12 Orange Line Vehicle Evaluation

This report presents the results of an engineering evaluation of the Massachusetts Bay Transportation Authority's No. 12 Orange Line rapid transit cars, accomplished at the Transportation Test Center, Pueblo, Colorado. The test program was carried out from February through April, 1981. The scope of...

Management of Urban Construction Programs Volume I: Guidelines for Developing a Project Management Plan

This report of the BRAB Committee on Management of Urban Construction Programs is intended to guide local authorities (such as transportation, water, and sanitary agencies) in developing management plans for executing urban construction projects. BRAB developed the report setting forth the...

Low-Profile, Lightweight Intermodal Railcar Volume II: Acceptance Test Plan

The Performance Specification and Acceptance Test Plan, respectively contained in Volumes I and II of this report, define the requirements for a low- profile, light-weight intermodal railcar. The Car specified here must be able to operate within restricted clearances when carrying either highway...

Locomotive Track Hazard Detector Program (LTHD) Interim Report

This interim report summarizes work performed by The MITRE Corporation for the Federal Railroad Administration Office of Rail Safety Research to develop a Locomotive Track Hazard Detector (LTHD). The objective of the LTHD program is to develop a simple and inexpensive unmanned track geometry...

Lightweight Vehicle Track Shunting

The objective of this contract was to determine the extent of the shunting problem on lightweight rail vehicles and identify research recommendations to resolve it. This study discloses that special precautions must be taken before single-unit lightweight railroad cars can be operated on common...

Investigation of Design Standards for Urban Rail Transit Elevated Structures

The purpose of this report was to review the various criteria for design of elevated rail transit structures currently in use by selected transit properties and to compile them in one source. The criteria was to be reviewed to determine the differences and similarities between them. An evaluation...

Interactive Simulation and Computer Graphics for the Quasi-Static Lateral Train Stability Model

The AAR's Quasi-Static Lateral Train Stability (QLTS) Model has been modified to include interactive graphics for a visual display of the simulated results. The interface program also allows the user to select the variables of interest prior to plotting the results. The program development utilized...

International Conference on Wheel/Rail Load and Displacement Measurement Techniques

The International Conference on Wheel/Rail Load and Displacement Measurement Techniques was held at the Transportation Systems Center (TSC) on January 19-20, 1981. The Conference was sponsored by the U.S. Department of Transportation (DOT) and Transport Canada. The U.S. DOT agencies involved in...
