Track Degradation at FAST

This report describes the Track Degradation Experiment performed on the FAST track at the Transportation Test Center, near Pueblo, Colorado. The railroad industry's need to allocate resources more effectively has prompted strong interest in methods of predicting when track will degrade...

Analytic Studies of the Effects of Track Geometry Variation

In this report, analyses are described which were used to aid in the planning of tests carried out on track in Bennington, New Hampshire in August 1982. These tests were designed to provide insight into practical aspects of track safety standards. General results for a fully loaded 100-ton hopper...

Analytical Descriptions of Track Geometry Variations

Analyses of recorded track geometry measurements were conducted to develop analytical representations of track geometry variations that exist on the U.S. railroad track. These analytical representations include: !) continuous stationary random variations described by power spectral density...

Grease Evaluations using the Hi-Rail Lubrication System at FAST

Previous testing of lubrication systems at the Facility for Accelerated Service Testing (FAST) have stimulated a general interest in grease performance. The hi-rail grease test was conducted to evaluate four types of lubricant when used with a hi-rail track lubricator. In this test, the grease...

Overview - FAST Lubrication Study

From October 1983 to November 1984, a lubrication study funded -by the Federal Railroad Administration was conducted by the Association of American Railroads at the Facility for Accelerated Service Testing (FAST) at the Transportation Test Center in Pueblo, Colorado. The FAST Lubrication Study...

Track Geometry Measurement System

This report describes the Track Geometry Measurement System (TGMS) developed fro the Department of Transportation under contract no. DOT-TSC-1367. This report also contains a summary of the results of the test program that was conducted to validate the TGMS under various static and dynamic...
