The Thameslink Programme has delivered a new fleet of new spacious, longer and more energy-efficient Class 700 trains manufactured by Siemens.

New class 700 trains began operating on the Bedford to Brighton route in July 2016 and are now also operating on Southern and Great Northern services. All new trains will be in service by summer 2018.

In total, 115 new trains and 1,140 new carriages have been built.


  • Higher capacity – new trains are longer with 8 or 12 carriages, providing more capacity into central London at the busiest times
  • Quicker journeys – new trains are more energy efficient, allowing faster breaking and acceleration
  • Better reliability – new trains are lighter, resulting in less wear to the track
  • More space – new trains have wider doors, aisles and more luggage space
  • Accessibility – new trains have improved access for passengers with reduced mobility
  • Live travel information – on all new trains, to help with your onward journey
  • Climate control – in all carriages on new trains
  • New station information screens – at Thameslink platforms in central London and on platforms 4 and 5 at London Bridge.

Two new depots have also been built by Siemens to maintain the new trains. The new depot at Three Bridges, near Gatwick Airport, was completed in July 2015. Meanwhile, the new depot at Hornsey, north London, came into use in summer 2016.

Providing new trains is just one way the Thameslink Programme is transforming north-south travel through London. We’re also improving rail connectionsmaking journeys more reliable, delivering better stations and leading the way through introducing new digital railway technology.
