The Government-sponsored £7bn Thameslink Programme is an ambitious 10 year programme to transform north-south travel through London.

When the Thameslink Programme is complete, 115 new trains will bring faster, more frequent, more reliable and better connected journeys for passengers.

The Thameslink Programme is delivering new infrastructure, better stations, new technology and new trains on an expanded Thameslink network.

These significant improvements will respond to the expected growth in passenger numbers now and into the future.

Thameslink Programme – nine years in 90 seconds!


Since 2009 the Thameslink Programme has rebuilt Blackfriars, Farringdon and London Bridge stations and delivered new railway infrastructure including the Borough Viaduct and Bermondsey Dive Under. The Thameslink Programme is part of Network Rail’s Railway Upgrade Plan to improve rail travel.


The Thameslink Programme is funded by the government through the Department for Transport (DfT).

Station, track and signalling works will be carried out by Network Rail working closely with Southeastern, Southern and Thameslink to minimise disruption to passengers. Thameslink will manage the introduction of the new train fleet and depots as well as the transition to new automatic train operating systems in central London and the new link to the East Coast Mainline.
