Chingford Sidings OLE Interlocking

The continuing demand for increased capacity through our rail depots is resulting in a trend to growing amounts of maintenance being carried out on sidings and stabling roads. This is resulting in staff working in potentially dangerous areas, where historically there has not been a need for depot protection.

The Chingford Sidings have been the most recent to invest in protecting the staff outside of the traditional maintenance shed.

Wimbledon- Points Converter System

Zonegreen have installed their points converter systems on both the Bogie Drop and the Wheel Lathe roads at Wimbledon TDM.

The points converter system provides a means of operating manual hand points remotely through the use of a hydraulic actuator. Allowing remote, automated operation of the hand points mitigates the risk posed to staff of operating heavy points leavers, and also negates the need to walk out to the points, removing the risk of slips, trips & falls as well as the threat of electrocution from the third rail.
