Revenue Track Gage Widening Tests Using the Track Loading Vehicle
ABSTRACT Gage widening tests were conducted using the TLV on portions of tracks of nine Class I railroads in North America. The measured unloaded gage and loaded gage, along with the computed delta gage (the difference between - loaded and unloaded gages) and track compliance (delta gage per...
Rail Operating Practices: NAFTA Report 1997
Following the coming into force of the North American Free Trade Agreement (NAFTA) in January, 1994, the Land Transportation Standards Subcommittee (LTSS) was established to consider, among other items, the compatibility of rail safety regulations relevant to cross-border operations. The LTSS...
Seismic Damage Assessment of Rail Structures in Japan after the January 1995 Kobe Earthquake
In the six weeks following the January 17, 1995 Great Hanshin Earthquake (also called the 1995 Hyogo-Ken-Nanbu Earthquake or the Kobe Earthquake) an enormous effort has been expended in the cleanup, demolition, repair and rebuilding of the damaged rail facilities. It is a credit to the rail owners...Report on the Functions of the Interstate Commerce Commission
This report examines a range of policy issues dealing with the economic regulation of surface transportation service (primarily freight) in the United States. Freight transportation represents a core element of our National economy. It provides U.S. manufacturers and consumers with access to...
Report No. 30 - Dynamometer-Induced Residual Stress in Railroad Wheels: Ultrasonic and Saw Cut Measurements
This is Report Number 30 in a series covering research performed by the National Institute of Standards and Technology for the Federal Railroad Administration. This report covers a project by the Materials Reliability Division to develop and test an ultrasonic system for measuring residual stress...Report No. 28 - Residual Stress in Induction-Heated Railroad Wheels: Ultrasonic and Saw Cut Measurements
[From the Introduction] This report deals principally with the ultrasonic measurement of residual stress in a set of 10 cast steel wheels of U.S. manufacture. They were all from the same heat, and so had the same chemical composition. Two wheels remained as manufactured with hoop compression in the...Northeast Corridor Improvement Project Electrification - New Haven, CT to Boston, MA: Final Environmental Impact Report, Supplement
This document is a supplement to the final environmental impact report (FEIR) published in October 1994 on the proposal by the National Railroad Passenger Corporation (Amtrak) to complete the electrification of the Northeast Corridor main line by extending electrification from New Haven, CT to...Modeling and Simulation of a Superconducting EMS-Type Maglev Vehicle/Guideway System
Computer simulation models are developed for predicting the dynamic performance of a magnetically levitated (maglev) vehicle with a superconducting (SC) electromagnetic suspension (EMS) traversing a flexible, multiple span, elevated guideway. A single Degree Of Freedom (DOF) vehicle model...High Productivity Integral Train Program - Iron Highway Phase II Evaluation
Evaluation tests of Iron Highway Phase II prototype show that the technical benefits predicted from the integral train design are attainable. The tests prove that the control and braking, loading and unloading, split ramp and platform suspension systems are ready to be engineered into production...
