The original entry into service was planned to be 2019 though delays in construction meant the first unit was not completed until mid-2020. COVID delays and problems with the units (the Aventra family in general have had a troublesome entry into service) has meant that as of October 2023 the Class 701 has yet to enter service! Entry into service is planned for December 2023.
The Class 701 has regenerative braking and wide gangways between cars as well as wide doors and efficient layouts. Something yet to be enjoyed by any passengers!
