Passenger Trail-to-Frieght Train Impact Test: Test Procedures, Instrumentation and Data

A full-scale passenger train-to-freight train impact test was performed on January 31, 2002 at the Transportation Technology Center, Pueblo, Colorado. The actual speed of impact, as measured by the laser speed trap, was 29.9 mph resulting in a large amount of damage to the leading cab-car, which...

Passenger Train-to-Frieght Train Impact Test: Test Procedures, Instrumentation and Data

A full-scale passenger train-to-freight train impact test was performed on January 31, 2002 at the Transportation Technology Center, Pueblo, Colorado. The actual speed of impact, as measured by the laser speed trap, was 29.9 mph (i.e., within .3% of the desired speed of 30 mph) resulting in a large...

Passenger Ride Quality of a Span Bolster Car with Freight Trucks

A test was performed to measure the ride quality of an eight axle Span Bolster Rail Car with freight trucks. The Federal Railroad Administration (FRA) and the Association of American Railroads (AAR), felt it necessary to examine the use of freight trucks and Span Bolsters on passsenger cars...

Selected Topics in Railroad Tank Car Safety Research Volume II: Test Plan for Accelerated Life Testing of Thermally Shielded Tank Cars

A test plan for the accelerated life testing of thermally shielded tank cars is described. The test program would be conducted at the DOT Transportation Test Center in Pueblo, Colorado. Eighteen tank cars would be included in the program. Five cars would be equipped with a jacketed thermal...

Passenger Rail Car to Train Impact Test: Test Procedures, instrumentation, and Data

Nucars Modeling in Support of Freight Car Tolerance Side Bearing Clearance Test

The objective of this investigation was to support previous (1993) on-track testing and analystical modeling to further determine the effect of side bearing clearance in the presence of various secondary suspension configurations on high c.g. cars. Further parameters investigated were track gage,...

Noise Test-Resilient Wheels Massachusetts Bay Transportation Authority Green Line

The purpose of this effort was to compare the noise and vibration characteristics of the Sab-V resilient wheels with those of Acoustaflex (resilient) and solid-steel wheels, which are both in current use on the Green Line of the Massachusetts Bay Transportation Authority (MBTA). Noise and ground -...
