Safety of High Speed Guided Ground Transportation Systems: Magnetic and Electric Field Testing of the Washington Metropolitan Area Transit Authority Metrorail System. Volume 2. Appendices.

The 51 appendices contain a detailed reporting of the magnetic field characteristics measured onboard the WMATA Metrorail and near associated facilities. The data have been consolidated and presented as efficiently as possible without resorting to summary measures which obscure the temporal or...

Safety of High Speed Guided Ground Transportation Systems: Magnetic and Electric Field Testing of the Massachusetts Bay Transportation Authority (MBTA) Urban Transit System. Volume 2. Appendices.

The safety of magnetically levitated (maglev) and high speed rail (HSR) trains proposed for application in the United States is the responsibility of the Federal Railroad Administration (FRA). Plans for near future US applications include maglev projects (e.g. in Orlando, FL and Pittsburgh, PA)...

Peacekeeper Rail Garrison Triplet Cars Track Worthiness Tests

Track worthiness tests were performed on a consist of three commercial depressed center flatcars (Triplet Cars) equipped with span bolsters to distribute heavy loads over four trucks. Tests were compared to, but not limited by, specifications in Chapter XI of the AAR's, Manual of Standards and...

A Survey of Railroad Industry Perceptions Regarding Needed Locomotive Cab Design Improvements

This survey was initiated by the Federal Railroad Administration (FRA) as part of the objective to improve locomotive cab safety. The need for and the definition of the survey was generated by the Locomotive Control Compartment Committee (LCCC) in its advisory role to the FRA. The survey was...

Safety Relevant Observations on the Ice High-Speed Train

The Federal Railroad Administration (FRA) is concerned with safety the of high-speed rail technology proposed for possible application in the United States. This report, one in a series of reports'-pertaining to high-speed rail technologies, presents an initial review of the German high-speed train...

Safety Aspects of New Trucks and Lightweight Cars, Car 2 Final Report

The Federal Railroad Administration and Association of American Railroads (AAR) sponsored a program to validate new techniques for the analysis and testing of safety and track worthiness aspects of new freight cars and suspension designs. The program involved subjecting a lightweight aluminum...

Field Testing of a Wayside Wheel Crack Detection System

A prototype crack detection system for railroad wheels has been developed by the National Institute of Standards and Technology (NIST) for the Federal Railroad Administration (FRA). The system is designed to detect the presence of thermal cracks in railroad wheels as they pass by an inspection...

Effect of Worn Components on Brake Forces in a Freight Car Rigging

A braking test program was conducted to investigate the extent of and causes for significant variations in braking thermal input to railcar wheels. The program consisted of the following tasks: -Brake force data was reviewed from previous test programs and computer simulations of brake forces in...
