Experimental Residual Stress Measurement of New and Used Commuter Rail Wheels

The report outlines the procedures used and presents the data obtained during the wheel saw-cutting portion of the Cracked Wheel Investigation. The purpose of the wheel saw cutting experiment was to determine the magnitude and direction of the residual stresses in a new, as well as a service-worn...

Safety of High Speed Guided Ground Transportation Systems: Review of Existing EMF Guidelines, Standards and Regulations.

To assess the state of knowledge about anticipated electric and magnetic field (EMF) exposures from electrical transportation systems, including electrically powered rail and magnetically levitated (maglev), research concerning biological effects of EMF exposure, with special emphasis on broad...

Evaluation of Immediate Actions Taken to Deal with Cracking Problems Observed in Wheels of Rail Commuter Cars.

The report is the first in a series of engineering studies on railroad vehicle wheel performance. Preliminary studies are summarized, involving evaluation of actions taken to respond to high rates of crack occurrence observed in the wheels of certain multiple unit (MU) power cars used in commuter...

Safety of High Speed Ground Transportation Systems: X2000 U.S. Demonstration Vehicle Dynamics Trials, Preliminary Test Report.

The report documents the procedures, events, and results of vehicle dynamic tests carried out on the ASEA-Brown Boveri (ABB) X2000 tilt body trainset in the U.S. between October 1992 and January 1993. These tests, sponsored by Amtrak and supported by the FRA, were conducted to assess the...

Evaluation of Rail Rollover Derailment Study

Research conducted by the Association of American Railroads at the U.S. Department of Transportation, Transportation Test Center, Pueblo, Colorado, led to an understanding of the gage widening behavior exhibited by several 125-ton gondola cars and locomotives in a 6-degree curve of the Facility for...

Safety of High Speed Guided Ground Transportation Systems: Comparison of Magnetic and Electric Fields of Conventional and Advanced Electrified Transportation Systems.

Concerns exist regarding the potential safety, environmental and health effects on the public and on transportation workers due to electrification along new or existing rail corridors, and to proposed maglev and high speed rail operations. Therefore, the characterization of electric and magnetic...

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)...

2014 C3RS User Group Meeting

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...
