It was used as part of the original Transport and Works Act order for the Thameslink Programme.

The future Thameslink services will increase the capacity on many routes into London, in particular the Midland Main Line, Great Northern, Brighton Main Line and some routes from Kent. The detailed specification of the train service, including stopping patterns, will be developed as part of the revised franchise arrangements that will be necessary to deliver the higher frequency Thameslink services.

Insufficient power supply and shorter platforms currently precludes the new trains from running between Cambridge and King's Lynn (see this FAQ).

Network Rail, through its Route Utilisation Strategies (RUS), has been examining the future use of the rail network on many of the routes impacted by the Thameslink Programme. You can view Network Rail's London and South East RUS here. You can also view Network Rail's South London RUS here which proposes terminating services from Sutton and Wimbledon at Blackfriars station.
