Crossrail awards traction power supply contract

By Peter MacLennan

Crossrail today awarded the contract for the high voltage traction power supply contract:

  • C644 – AC Joint Venture (Alstom Transport and Costain Limited)

Crossrail will operate a high-frequency metro service of up to 24 trains per hour during the peak between Whitechapel and Paddington through new tunnels under central London.

The scope of works includes the provision of traction power, distributed within Crossrail’s central section extending from Royal Oak Portal in the west to Pudding Mill Lane in the east, splitting at Stepney Green Junction and running to Plumstead Portal in the southeast.

The works will involve the construction of a feeder station at Pudding Mill Lane where power from the 400 kV National Grid network will be converted down to 25 kV before being fed into the overhead line equipment that will power the new Crossrail trains. A separate feeder station will be constructed by Network Rail at Kensal Green.

Four high voltage auto transformer stations will be also constructed at Westbourne Park, Stepney Green, Custom House and Plumstead to maintain the voltage along the line.
