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...

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...

Investigation of Local Commutation as Applied to Linear Synchronous Motors for Use as a Maglev Propulsion System

The Locally Commutated Linear Synchronous Motor (LCLSM) concept was analyzed and demonstrated. Design and analysis of an 8.1 Megawatt propulsion motor for a 100 Mg Maglev vehicle resulted in a LCLSM system capable of generating smooth thrust with non-overlapping individual propulsion coils. Each...

Field Testing of High Degree Revenue Service Track for Buckling Safety Assessment

This report presents the results of a field study of high degree curves in continuous welded rail (CWR) territory. This program was conducted at two test sites: a 10 degree curve on the Atchison, Topeka, and Santa Fe (ATSF) Railroad near Sante Fe, NM, and a 12 degree curve on the Norfolk Southern (...

Wheel Peeling Experiment - Analysis of Commuter Rail Wheel Thermal Cracks

This report outlines the procedures used and presents the data obtained during the wheel peeling portion of the Cracked Wheel Investigation. The procedure was conducted by ORX, Inc., Tipton, Pennsylvania from April 6 to April 9, 1992. Its purpose was to measure and record the physical...

Vent and Burn Method of Field Product Removal

The Federal Railroad Administration tasked the Association of American Railroads, Transportation Test Center Hazardous Materials Training Center, to research and develop safe, reliable operating procedures for of the Vent and Bum method of field product removal, and to define when or if this...
