NOISE DEGRADATION OVER TIME IN RAIL RAPID TRANSIT CARS
The purpose of this effort was to study the degradation of noise quality of selected cars over time, and to relate this degradation to treatment events if possible. To this end, three trains were observed monthly for a period of seven months in an extensive collection and analysis effort. The three car types studied were: IRT cars comparable to the R17; IRT cars (R17), with a special design feature the 'Traction Fault Detector'; and R46 cars. Because of the substantial measurement problems encountered, the project has in fact two sets of major results: (1) those relating to the novel data collection and analysis methods employed; and (2) those relating to wheel-rail interaction and degradation.
