The regional managing director at Network Rail Wales & Western has resigned, after a prolonged delay on the approaches to London Paddington left passengers stranded in blacked-out trains.

Michelle Handforth is stepping down but will continue to work on certain projects until her successor is appointed.

An incident near Paddington on 7 December damaged the OHLE, disrupting Great Western Railway, Heathrow Express and TfL Elizabeth Line services. Passengers complained that they were trapped in stalled trains for more than three hours and received no explanations from staff during the hold-up.

The Office of Rail and Road had already launched an investigation into performance on Wales & Western, saying that it had continued to deteriorate while it had stabilised elsewhere.

It is reported that Ms Handforth had already decided to leave before the incident on 7 December, but this has yet to be confirmed.

In a letter to staff, she said: ‘It's been a real privilege to work with you all through the highs and lows of the past couple of years, and while this decision is a real wrench to me, I believe it is the right one for me, my family and the business.

‘It has been such an honour to lead this region since joining the business in August 2020. Over that time we have faced an incredible range of challenges, but your support, friendship and good humour has been consistent throughout.

’I am extremely proud of the achievements we have made together and while times feel tough right now, I know that a bright future for Wales and Western lies ahead.’
