Project: CTRL Section 2
Client: Rail Link Engineering Ltd
Section 2 of the Channel Tunnel Rail Link (CTRL) is a new section of high speed line, 39.4 km in length. The extension is from the existing CTRL section 1 at Singlewell to London St Pancras.
The route includes a 2.5 km tunnel under the Thames near Dartford, and a 19 km tunnel, emerging over the East Coast Main Line near St Pancras.
There are new stations at Ebbsfleet and Stratford International, with a new depot at Temple Mills to the north of Stratford. When the second section of the CTRL is opened, all Eurostar trains will run to St Pancras International instead of Waterloo International. The line has now been renamed High Speed 1.
The CTRL is signalled with TVM430 Cab Signalling and the Network Rail lines are signalled with Route Relay Interlocking (RRI), Solid State Interlocking (SSI) and Geographical Relay Interlockings.
DEG Signal Ltd was commissioned to provide an Independent Safety Assessment of the interfaces between cab signalling and conventional lineside signalling. Each interface was assessed in detail and the reports were presented to the System Review Panel (SRP) for acceptance.
