Operator Planning Suite

The planning of train maintenance operations is still commonly conducted on a big whiteboard located in the operations control room, on which the train units that require servicing, maintenance tasks, arrival and departure times are listed. These are updated manually.

Zonegreen’s Operator Planning Suite, as a multi-user, web-based graphical task planning application, is a cost-effective replacement of the whiteboard. It consists of two main views: a graphical layout representing the depot on which users can position trains and assign maintenance tasks, and a tabular layout to plan trains’ scheduled arrivals and departures.

Skirt Detector – Rail Depot Obstacle Detection System

The ‘Out of Gauge’ Warning System ensures that there is no gauge obstruction threatened by vehicles leaving the depots such as access panels left open, broken CET fuelling hoses, collision damage etc.

The innovative system works by using a low power red laser diode to detect the distance to the side of the vehicle. If the sensor detects any kind of obstructionit will trigger an alert on the outbound visual warning board and illuminate a warning board on the depot exit road.
