Abstract
A system is disclosed for monitoring condition of a railways installation such as a points machine. The system includes a plurality of sensors (S1, S2, S3-SN) associated with elements of the installation for monitoring parameters indicative of operating capability of the installation. The system includes means (12, 23) for processing the monitored parameters to determine whether the parameters are changing relative to reference values and to determine whether the changes are indicative of an increased risk of malfunction in the installation. The processing means may include a digital computer programmed with condition monitoring and fault detection software. A method of monitoring condition of a railways installation is also disclosed.
