ON-BOARD RCM SYSTEM
Cameras have been mounted on-board a ScotRail HST Power Car monitoring temperatures of the engine and the alternator. The cameras can be remotely accessed by Rail Innovations using the system’s independent 4G Router in order to view the live video, to download thermal recordings or to change the camera settings. The cameras can be configured with up to 20 zones per camera, each assigned with its own temperature threshold.

The camera mounted on the central equipment cubicle of the Power Car Clean Room, monitoring the alternators (traction & auxiliary) and some of the equipment cabinets.
The trial cameras have zones set up to monitor the temperatures of the four turbochargers and cylinder head covers on the diesel engine, plus the alternator casing and exhaust system, plus electrical equipment cabinets - including the Rail Innovations equipment cabinet!

Individual temperature limits have been assigned to each zone and the trial has proven that emails are automatically sent to Rail Innovations in the event that any one of these thresholds are exceeded. Rail Innovations is then in a position to advise the TOC/FOC so that the operator can intervene with Planned Preventative Maintenance to prevent an in-service failure.
