Rail Vehicle Dynamics Model Validation

The validation of mathematical models of rail vehicle dynamics using test data poses a, number of difficult problems, which are addressed in this report. Previous attempts to validate rail vehicle models are reviewed critically, and experience gained in validating dynamic models of aircraft and...

Dead Line Testing of Pantographs on the RTT Catenary System

The tests described in this report were carried out by the Transportation Test Center to verify the newly constructed overhead catenary system on the Railroad Test Track (RTT) and the pantographs to be used on it. The data produced included height and stagger measurements in support of the...

An Experimental Evaluation of a Full-Scale Single-Sided Linear Induction Motor with Different Reaction Rails: Volume II - Supplementary Data

This document presents supplementary data to Volume I: Test Results. It contains computer plots of all valid onboard data processed for 125 test runs, including baseline reaction rail tests for the 10- and 5-pole SLIM with dc and ac excitation, and solid iron reaction rail tests for the 10-pole...

An Experimental Evaluation of a Full-Scale Single-Sided Linear Induction Motor with Different Reaction Rails: Volume I - Test Results

This document is the final volume in a series of reports presenting the results of an extensive test program involving the linear induction motor research vehicle (LIMRV). Specifically, this report describes the final LIMRV test activity with a single-sided linear induction motor (SLIM). The...

A Perspectival Review of Rail Behavior at the Facility for Accelerated Service Testing

The rail metallurgy tests which have been undertaken at the Facility for Accelerated Service Testing (FAST) are described. The best of the premium metallurgies has been found to wear approximately three to four times better than standard rail in the unlubricated regime. In the lubricated regime,...

Wind Tunnel Tests of Trailer and Container Models to Determine the Independent Influence of Height and Gap Spacings and Trailer Undercarriage Shielding on Aerodynamic Forces Occurring During Railroad Transport

A series of wind tunnel tests have been run on scale model trains of 40 ft. containers and trailers. The models were 1/43 scale. A train of five models was used with forces and moments measured on the center model. A variety of spaces were used between the models. The height of the container models...

Rail Bus Test Observations on the Boston and Maine Railroad - January to February, 1980

This report summarizes the characteristics of the Leyland Experimental Vehicle (LEV-1) and the test program conducted on the Boston and Maine Railroad from January to February, 1980. It contains an introduction and review of the program, a brief summary of the test results, and generalized...

Performance of a Single-Sided Linear Induction Motor with Solid Back Iron and with Various Misalignments - Volume I

A test facility was designed and built to measure all aspects of the performance of a single-sided high-speed linear induction motor with solid back iron over a wide range of frequency, speed, and excitation. The facility was equipped and instrumented to measure all the usual performance parameters...

Performance of a Linear Synchronous Motor with Laminated Track Poles and with Various Misalignments

A test facility was designed and built to measure the performance of a single-sided high speed homopolar Linear Synchronous Motor with laminated pole pieces over a wide range of frequency and excitation levels. The facility was instrumented to measure performance at the machine terminals, flux...

Freight Car Fatigue Test on FAST

As a result of observed cracks in the fabricated center sills of many freight cars in the FAST consist, a special Fatigue Analysis Test (FAT) was conducted on the FAST Track during August and September of 1978. This report provides an analysis of the static and dynamic strain data from a base case...
