The Liverpool City Region Merseyrail network could be expanded after testing of the new fleet showed it can travel for 135km using only battery power.
It had been hoped the long-awaited new class 777 trains would start to arrive on the local rail network before the end of 2022, but last week it was confirmed passengers will have to wait until the new year to step on one of the modern, new trains.
The new fleet of state-of-the-art trains were first purchased for the Liverpool City Region back in 2016 for £500m, but their roll-out has been delayed because of various factors including the pandemic and a long-running industrial dispute with the RMT union.
