New train route scheduled to carry 200 million passengers per year across London, by 2018…


Siemens will supply the signaling and control equipment for the 21 kilometer long Crossrail tunnel in London, linking up the local transport system to the suburban regional services of Network Rail. The project company “Crossrail” has placed an order with the consortium made up of Siemens and Invensys. The business is worth a total of around 60 million euros. Commissioning of the overall line is scheduled for the end of 2018.

In the Crossrail tunnel, the trains will be governed by means of radio Communications-Based Train Control (CBTC). On the westward long-distance route the European Train Control System (ETCS) Level 2 is installed; the eastward direction features the local Train Protection Warning System (TPWS). Dynamic switchover between the three control systems will ensure smooth integration of the differing lines.

For the core part of the line, Siemens will install the radio-based control system Trainguard MT with Automated Train Operation (ATO), the operations control system Vicos and the radio transmission system Airlink, including the integration between ETCS, TPWS and CBTC. The consortium partner Invensys will provide the interlocking equipment, along with components for outside facilities, and will attend to installation. Supply of in-vehicle units, as well as a service agreement, will be the subject of separate contractual terms.

Beneath the center of the metropolis, the 21 kilometer long rail tunnel will constitute a twin-track East-West connection, linking the Great Western Main Line at its present terminus, Paddington station in West London, with the Great Eastern Main Line at Stratford station in East London. The tunnel is the centerpiece of the London Crossrail project comprising a roughly 118 kilometer long line from Maidenhead and Heathrow in the West to Shenfield and Abbey Wood in the East. As of 2018, up to 24 trains per hour are scheduled to travel along the core network, carrying 200 million passengers per year and easing the load on the London Transport system.
