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 the Deleterious Effects of Electro-Magnetic Fields on Steel Rebar Used in Guideways for EDS Maglev Systems: Volume I, Summary

[From the Introduction] This report summarizes work done on an FRA contract to study the important interactions of magnetic fields with rebars. The work was done as 5 distinct tasks: Task 1 — Perform Magnetic Field Analysis; Task 2 — Conduct Literature Search; Task 3 — Characterize Interactions/...

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...

Highway-Rail Crossing Accident/Incident and Inventory Bulletin: No. 17 Calendar Year 1994

[From the Introduction] The seventeenth annual report, issued by the Federal Railroad Administration (FRA) Office of Safety, combines highway-rail crossing accident/incident statistics with the National highway-rail crossing inventory. Accident/incident data is compiled from monthly reports filed...

High Productivity Integral Train Program - Iron Highway Phase II Testing

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 (...

A World of Change, Volume 1: FAST/HAL Test Summaries

[From the Foreword] Welcome to A World of Change: 1st Annual AAR Research Review, November 6-9, 1995. Our four-day event focuses on four aspects of the activities carried out by the Association of American Railroads' Research and Test Department at the Transportation Technology Center (TTC), in...

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...
