Channel Tunnel Rail Link Maintenance

In accordance with Carillion Rail’s Infrastructure Maintenance Contract, a professional and highly skilled team of technical staff has been centrally involved with maintenance of CTRL infrastructure since the award of the contract in August 2002.

CTRL infrastructure maintained within the scope of the contract includes:

• 25kV overhead line equipment

• Cutting edge signalling installations, such as the CTRL-wide TVM 430 in-cab signalling system, as well as coloured light signals and the KVB train protection system in the St Pancras area

• High speed turnouts (300km/h) incorporating swing-nose crossings

• State-of-the-art fibre-optic data transmission networks and telecommunications systems

• Mechanical and electrical equipment, such as pump stations, tunnel fire mains HVAC systems, tunnel ventilation systems and UPS installations

• Maintenance of UIC60 track systems between Eurotunnel and St Pancras International Station

• Operation and maintenance of rail plant based in a new, purpose-built infrastructure maintenance depot sited at Singlewell (near Gravesend) in North Kent

• Landscape management is an integral element of the contract. Some 220ha of planted woods and wildflower grassland areas, 23km of hedgerows and 14ha of plantings on translocated, ancient woodland soils are cared for by a dedicated environmental team. The CTRL passes through a number of SSSIs and water source protection zones which require particular consideration.

The Carillion team based at Singlewell is extremely proud to have partnered Network Rail in both Phase 1 and Phase 2 of the CTRL which, with the opening by Her Majesty Queen Elizabeth II of High Speed 1 to St Pancras on 14th November 2007, comprises the UK’s first high speed operational railway.
