Seismic Awareness: Transportation Facilities : A Primer for Transportation Managers on Earthquake Hazards and Measures for Reducing Vulnerability Plus Appendices

The purpose of this report is to alert managers and operators of transportation enterprises, in both the public and private sector, to the dangers of earthquakes to buildings and possible precautions to be taken. The nature of seismic hazards in the U.S. is described. These include the probability...

Laboratory and Field Testing of NYCTA Power Frequency Track Circuits

This report addresses the possible electromagnetic interference between the electronic AC propulsion control systems and the signaling and train control systems. The potential exists for AC-drive propulsion systems to cause EMI that can adversely affect the operation of NYCTA's power-frequency...

Test Results Report : Dual Disc/Tread Braking and Reduced Pressure Braking Evaluation Programs

This report is the Test Results Report for the Dual Disc/Tread Brake Test. Data logs and records associated with this test are published separately in the Test Events Report Dual Disc/Tread Braking and Reduced Pressure Braking Evaluation Programs, Report No. FRA/ORD-8l/21. The Dual Disc/Tread...

High Cant Deficiency Testing of the LRC Train, the AEM-7 Locomotive, and the Amcoach

Increasing the speed of passenger trains in existing curves has been proposed as an alternative to changing curve radii for the purpose of reducing trip times on the Northeast Corridor. This test evaluates safety at high cant deficiency by comparing direct wheel/rail force measurements to safety...

Railroad Research and Development : Summary Results of 70 Ton Boxcar Testing

Tests were performed at the Transportation Test Center in Pueblo, Colorado on a 70 ton boxcar with Barber S-2C trucks in April and May of 1981. The objective of the tests was to provide definition of the dynamic properties of the freight car for application to the validation of a mathematical...

Wheelclimb Derailment Processes and Derailment Criteria

The most widely accepted criterion for wheelclimb derailment defines an upper limit for safe operation on wheel/rail contact forces on the climbing wheel, with the limit varying with time duration of the forces. For dynamic wheelclimb processes with significant lateral velocities, lateral forces...

Amtrak/Knorr Disc Brake Study : Volume 1 - Final Report

This report describes the Amtrak/Knorr Disc Brake Study which was developed: (1) To evaluate candidate replacement disc brakes for the Knorr discbrakes presently in use on Amfleet and Turboliner cars. (2) To explain the cause of the loosening of the attaching pins and the excessive wear...

Amtrak/Knorr Disc Brake Study : Volume II - Appendices A through I

This volume contains the following appendices to Volume I, Final Report: Appendix A - Wheel Condition Effects Appendix B - Effects of Cyclic Loads on Pin Wear Appendix C - Over-the-Road Test Acceleration Data from the Boston Run Appendix D - Over-the-Road Test Acceleration Data from the...

Brake System Design Optimization- Volume II: Supplemental Data

This report presents supplemental data which support Volume I, A Survey and Assessment, DOT-TSC-FRA-78-1,I,FRA/ORD-78/20,I, dated June 1978, 140 pages. A detailed description of the functional performance of each freight car air brake system component is provided. This is followed by a discussion...
