Improved Passenger Equipment Evaluation Program: Technology Review - Wheels, Axles, Couplers
The status of two foreign rail technologies is analyzed in this report. The two technologies are Wheels and Automatic Couplers. The wheel development program for the French TGV is reviewed. It illustrates the application of classical wheel design to modern high-speed rail transport. The...Freight Car Truck Design Optimization: Vol. I - Executive Summary
This report has been prepared by the FRA as an overview of work accomplished by the Southern Pacific Transportation Company for FRA. It reviews and gives conclusions of Phase I of the Truck Design Optimization Project (TDOP). It represents the first of a six volume published set. See also: Vol. II...Freight Car Truck Design Optimization: Vol. V - Critique of Frequency Domain Model - Equations of Motion
The mathematical model developed by the Southern Pacific Transportation Co. (SPTCo) during the course of Phase I of the Truck Design Optimization Project (TDOP) is discussed. The equations of motion for a slightly simpler model with simpler nomenclature, which resulted from MITRE/METREK's review...Freight Car Truck Design Optimization: Vol. II - Phase I Final Report

FRATE, Volume I: User's Manual
FRATE (Freight Car Response Analysis and Test Evaluation) is the name of a digital computer program which numerically solves the structural dynamic equations of motion of a single railroad freight car excited by wheel/rail interface motions. The Federal Railroad Administration (FRA) has sponsored...Flaw Detection in Rails
The Physical principles and techniques of magnetic and ultrasonic flaw detection in rails are given. The intended use, working principles and layout of various rail flaw detector systems and the procedure for working with them are described. The methodology of rail inspection, both in the field...
Engineering Data on Selected High Speed Passenger Trucks
The purpose of this Project is to compile a list of high speed truck engineering parameters for characterization in dynamic performance modeling activities. Data tabulations are supplied for trucks from France, Germany, Italy, England, Japan, U.S.S.R., Canada and The United States.
