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.
Economics of Concrete- and Wood-Tie Track Structure
This report presents results from an evaluation of the economic benefits of concrete- versus wood-tie track. The analysis includes the life-cycle capital, maintenance, and renewal costs for concrete- and wood-tie track for four specific test cases and traffic ranges from 15 to 40 annual million...Draft Gear/Cushioning Unit Optimization for Train Action - Interim Report
This interim report describes the work done to date under Task 5 - Draft Gear/Cushioning Unit Optimization of the Track Train Dynamics program. Existing analysis tools for estimating train action forces were reviewed. Alternative approaches for analytical representation of currently used draft...Coupling System Design Optimization - A Survey and Assessment of Automatic Coupling Concepts for Rail Freight Cars
