The two Canal Tunnels link the low-level platforms at St Pancras International on the Thameslink core section with Belle Isle Junction near Finsbury Park station on the East Coast Main Line.
Built at the same time as the redevelopment of St Pancras station between 2004 and 2006, the intention was that the tunnels would be used to provide this essential new link to the Thameslink route. Since then the Thameslink Programme has installed track, power, signalling and safety systems to run services through the tunnels.
Trains travelling through Canal Tunnels will provide up to eight of the possible 24 services an hour which will travel through central London when the Thameslink Programme is completed.
The Government-sponsored Thameslink Programme is transforming north-south travel through London. Find out more about how the Thameslink Programme is creating new railway infrastructure and stations, leading the way in adopting new digital technology and providing new trains.
