Abstract
The background and constraints involved in condition monitoring of railway point operation are reviewed and discussed. An approximate method to replicate maladjustment, based on industry experience, is proposed and a computer simulation of the point machine and load is introduced. In view of uncertainty in results, a mechanical solution was preferred and the design and implementation of a simulated trackside environment test system and the instrumentation and measurement techniques used to gather practical data are described. In view of the severe railway environment, only electrical quantities were monitored using non-invasive sensors. A comparison is made with site data. Conclusions include the estimated payback available from implementing the condition monitoring system.
