Shore supplies are provided at Railway Stations, Depots, and Stabling Sidings as a facility to pre heat and condition the trains being stabled.

Historically until the early 1990s, shore supply equipment was specified, procured and controlled by the British Rail Board headquarters in London. Tecnivel UK/Charnvel Ltd. was one of two companies on the list of preferred suppliers for the switchgear, line side pillars and site commissioning of the complete installation. Since privatisation of the railways, Charnvel, have in most cases, provided the complete package for the project, including the HV ring main unit, power transformer, plugs, receptacles, flexible leads and stowage units, and at some locations diesel generators.

Over the years there have been a number of technical specifications issued for the supply of this equipment, but the requirements apart from modern practice, legislation and national standards have not changed the content and operation of the equipment.

It is still possible to install a new line side pillar to operate on a 1970s switchboard and visa versa.

Shore supplies are provided in both 400V TP and 850V 2P versions depending upon the type of stock. As some stock is capable of accepting 850/1000V we have upon request provided 1000V units at some locations.

The primary difference between the 400 and 850/1000V units being the voltage rating of the circuit breakers busbars and control protection fuses. The operation of the equipment is identical.

Options

• 400 / 850 or 1000 volt.
• PLC controlled load dumping system ('Last on first off' as standard).
• Mobile line side pillar options.
• Compact generator and shore supply feeder units with integral diesel tank and shore supply controls, suitable for mobile shore supply applications and emergency use.
