Peacekeeper Rail Garrison Test of Engineering Model Maintenance Car

Tests were performed on the Peacekeeper Rail Garrison Maintenance Car {MC), according to specifications in Chapter XI of the AAR's, Manual of Standards and Recommended Practices. The unloaded MC was subjected to limited service worthiness testing. The tests, performed on the loaded MC, included...

Examination of Cracks in Wabco and Knorr Disc Brakes

The Knorr and Wabco disc brakes were examined for the cause of cracking and why there is a difference in the type of cracks found in the two designs. Microstructure, microhardness, hardness, composition, and crack surfaces were investigated. Little difference was noted between the two materials....

Safety of High Speed Ground Transportation Systems

The objective of this study is to develop qualitative and quantitative information on the various braking strategies use in high-speed ground transportation systems in support of the Federal Railroad Administration (FRA). The approach employed in this study is composed of two steps: first, build...

Wayside Energy Storage Study: Volume IV- Dual Mode Locomotive, Preliminary Design Study

This is the fourth volume of a four volume report entitled the Wayside Energy Storage Study, which comprises the following volumes: Volume I, Summary; Volume II, Detailed Description of Analysis; Volume III, Engineering Economics/Analysis: Data and Results; Volume IV, Dual Mode Locomotive/...

Railroad Passenger Ride Safety

Safety requirements for high cant deficiency rail passenger service address the dangers of vehicle derailment, track damage and unreasonable risks to standing passengers of falling. Safety criteria concerning vehicle derailment and track damage have been weeldeveloped. Those applicable to passenger...

Real Time Hunting Mitigation: Sensor Systems to Detect Hazardous Conditions in High Speed Rail Operations, Phase I Report

Using advanced digital signal processing, IEM analyzed truck vibration data and identified the specific vibration signature of hunting. This signature clearly differentiates hunting from signals generated by such transient phenomena as switch points and rough track. this approach has been confirmed...

Results from the Car Coupling Impact Tests of Intermodal Trailers and Containers

Results are presented from the car coupling impact and lift/drop tests which were conducted during April 1985 at the Transportation Test Center, Pueblo, Colorado, under the Safety Evaluation of Intermodal and Jumbo Tank Hazardous Material Cars Program. The program was conducted to develop...

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...

High Cant Deficiency Operation of the Talgo Train on the Pacific Northwest Corridor

The U.S. Federal Railroad Administration (FRA), Amtrak, the Burlington Northern Santa Fe Railway (BNSF) and the Departments of Transportation for the states of Washington and Oregon, in an effort to improve rail passenger service on the Pacific Northwest Corridor, have initiated a co-operative...

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...
