The signalling system will incorporate automatic train operation to support a high-frequency metro service.
The five shortlisted organisations that will be invited to tender later this year are:
- Bombardier Transportation UK
- Invensys Rail
- Siemens PLC
- Signalling Solutions
- Thales Rail Signalling Solutions.
Crossrail will operate up to 24 trains per hour during the peak between Whitechapel and Paddington through the 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.
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.
The signalling system in the central section is expected to be capable of enhancement to 30 trains per hour through the central section at a later date.
