The British Rail Class 720 is a class of electric multiple units to be built by Bombardier for Greater Anglia. They will be operated on the suburban lines into London.[3] All 111 trains will be introduced from 2019-2020.[3]


The units will be fully air conditioned, seat back tables and power sockets, passenger-loading / capacity indicators in passenger information system and on-train Wi-fi.[3] The seating will be in a 3+2 arrangement, and cantilevered off the floor to create more space for bags.[4] Each five car unit will be 122m long and provide 544 seats.[5] Similarly to London Overground units, trains will have through gangways to encourage passengers to spread out across the train.[3] The trains are being financed by Angel Trains.[5][6]


In August 2016, Greater Anglia was awarded the East Anglia franchise with a commitment to replace all of the existing fleet. As part of this an order was placed with Bombardier for 89 five-carriage and 22 ten-carriage Aventra electric multiple units for use on suburban services on the West Anglia and Great Eastern Main Lines.[7][8][9] They will be built at Derby Litchurch Lane Works.[10][11]

An interior mockup was unveiled by Greater Anglia in September 2017, following a consultation which solicited 1,000 responses from members of the public.[3] Changes made included replacing the originally intended Fainsa seating with softer seating from Kiel as well as the addition of seat back tables.[3]

Production began in February 2018[12], with the first five-car units due into service in March 2019, followed by the ten-car units beginning in April 2019.[13]


The Class 720 will resemble the Class 345 and Class 710 being constructed for Crossrail and London Overground respectively. However, owing to the services that they will operate, the 720s will be built with a faster top speed of 100 mph (161 km/h).
