Crossrail last week confirmed the shortlist for its non-traction high voltage power supply contract and its intention to issue an invite to tender later in the year.
The five are: ABB; the Alstom Transport and Costain joint venture, AC; Balfour Beatty Engineering Services; the Siemens and J Murphy & Sons joint venture, Rail Power; and UK Power Networks (Commercial).
Crossrail will operate a high-frequency metro service of up to 24 trains per hour during the peak between Whitechapel and Paddington.
The scope of works includes the provision of electrical power, distributed at 22kV or 11kV, within the tunnels and surface sections of the central section of Crossrail. The network will extend 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 South East.
The system will also provide a power supply for use at stations, shafts and portals for all local and railway system loads with the exception of the traction power for the trains.
