HS2's latest reset ditches autonomous train tech to get project back on track

HS2 has abandoned autonomous train operation (ATO) technology and reduced the maximum speed of its railway from 360 km/h to 320 km/h as part of a cost-saving and schedule-stabilization reset. The changes, recommended by HS2 Ltd and endorsed by the Department for Transport, aim to save £1-2.5 billion and accelerate the project's completion, though the National Audit Office (NAO) warned of uncertain savings and reduced long-term benefits.
