Update on the Thameslink Programme

The Department for Transport is sponsoring a £7 billion programme to increase passenger capacity on the Thameslink route through central London. The programme involves the improvement of tracks, signalling and stations, a new fleet of trains and new franchise arrangements for running the passenger service on the Thameslink route. Our previous report Progress in delivering the Thameslink programme focused on the infrastructure and rolling stock delivery up to 2013.

This study will provide an update on our 2013 report, examining how the Department has managed cost and schedule pressures since we last reported and what progress has been made to ensure that the long term passenger and economic benefits of the programme are delivered.

Since 2015, train services on the Thameslink Southern Great Northern (TSGN) franchise have been subject to significant disruption, particularly on the Southern services. Alongside our work on the Thameslink Programme, we also plan to report on the Department’s management of the TSGN franchise.
