Application – On Load

The Road 630V DC is then fed directly from the Contactor to the Power Pedestal.

Two 110V AC control supply is also derived from the respective Contactor panel.

The Shore Supply Plug is fitted with a Plug Engaged sensor which inhibits the application of Traction Power to the train unless a magnet in the train receptacle to detected.

The Pedestal supplies Traction Power to trains in depot lifting sheds via a Shore Supply Plug. The Shore Supply Plug is stowed in the area underneath the Local Operator Station and the cable is coiled either on the end of a middle road enclosure or on the boom or wall bracket for outer road enclosures.

There is a frangible link that disconnects under strain thus preventing damage to the pedestal should the train be moved out of the depot with the plug remaining in the train receptacle.

Shore supply status beacons are positioned on top of the Power Pedestal enclosure
