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...

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...
