Abstract

Efficient inspection methods are strongly in need for rail track maintenance to improve safety and economy of railway operation. The possibility of utilization of ordinary service vehicles for rail track monitoring is studied in this paper. By using service vehicles, it is possible to cover the entire network with much higher density and frequency compared with the conventional inspection with designated personnel and vehicles. Monitoring system to measure floor vibration of the vehicles is developed so that installation can be made without modification of the vehicles, and to reduce cost for sensors and systems. Then the developed system is applied to an actual railway and measurements with different time instances are compared. By looking at the root mean square (RMS) acceleration responses, it is found that the responses at the same location are stable with repetitive measurements. It is also observed that repair and deterioration of track beds cause significant change in measurement.
