SUBJECT: Track/Train Interactions
KEYWORDS: Wheel/Rail Wear Performance, Curved Track, Wear Rates
ABSTRACT: This report describes the results of a test series carried out on the Tight Turn Loop at the Transportation Test Center to assess the curving and wheel/rail wear performance of a transit vehicle negotiating a very tight turn. Tests were performed on unlubricated rail to ensure constant coefficients of friction. Wheel/rail forces and angles-fo-attack were recorded using onboard and wayside instrumentation. Wear rates were systematically recorded. The report details the test setup adn results, stressing the correlation between experimental data and computer model predictions. The report concludes with recommendations for improved experiemental techniques, suggesting developments to the computer model and a proposal for further testing on the Tight Turn Loop.
