Crossrail confirms signalling system shortlist

By Peter MacLennan

Crossrail confirms signalling system shortlist
  • New railway signalling and control system will enable operation of 24 trains per hour during the peak between Paddington and Whitechapel

  • Signalling and control system to be designed to support enhancement to 30 trains per hour through central section at a later date

Crossrail today confirmed the shortlist for the central section signalling system. The following organisations will be invited to tender later this year;

  • Bombardier Transportation UK Limited
  • Invensys Rail Limited
  • Siemens PLC
  • Signalling Solutions Limited
  • Thales Rail Signalling Solutions 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. Construction of the new tunnels will get underway in spring 2012 when the first tunnel boring machine is launched from Royal Oak.

The new signalling system will incorporate Automatic Train Operation to support the delivery of a reliable, high-frequency metro service and must also be capable of enhancement to 30 trains per hour through the central section at a later date.


Notes to Editor:

The Invitation to Tender is due to be issued in late 2011.

This contract covers the design, manufacture, supply, installation, testing and commission of an automatic train control system for Crossrail’s central section.

The new signalling system will be installed along the Crossrail route between Portobello Junction (west of Paddington) on the Great Western Main Line, Pudding Mill Lane Junction on the Great Eastern Main Line in the east and Abbey Wood sidings in the south-east.

Crossrail’s services will operate in Automatic Train Operation (ATO) mode with Automatic Train Protection (ATP) in the central operating section from Portobello Junction to Pudding Mill Lane / Abbey Wood.

Due to the integration of Crossrail’s central section with the existing National Rail network, Crossrail services will need to operate with signalling and safety systems installed at either end of the Crossrail tunnels.

About Crossrail:

Crossrail will run 118 km from Maidenhead and Heathrow in the west, through new twin-bore 21 km tunnels under central London to Shenfield and Abbey Wood in the east. It will bring an additional 1.5 million people within 45 minutes commuting distance of London's key business districts. 

When Crossrail opens it will increase London's rail-based transport network capacity by 10%, supporting regeneration across the capital, helping to secure London's position as a world leading financial centre, and cutting journey times across the city.

Crossrail is being delivered by Crossrail Limited (CRL). CRL is a wholly owned subsidiary of Transport for London. Crossrail is jointly sponsored by the Department for Transport and Transport for London.
