Class 720 Aventra

The Class 720 is part of the Bombardier Aventra family like the Class 345 and is being built for Greater Anglia and c2c to replace a number of older electric multiple units such as the Class 317 and 321. All units on order are five-car sets, earlier plans for a ten-car version were changed. The first Class 720s were built in late 2018. Originally it was planned for the Greater Anglia 720s to enter service in 2019 on services out of London Liverpool Street though delays to testing and software issues pushed that back until November 2020.
