An Aberdeen-based railway boss has stepped down from her role just days after infrastructure problems left hundreds of passengers stranded in carriages for hours in the dark in west London.
Michelle Handforth has resigned from her position as managing director for the Wales and Western region at Network Rail.
The BBC said she had made the decision to resign before the west London incident, after recognising the challenges of the role.
Earlier this month, passengers were stuck in cold and dark carriages for hours when overhead electric cables were damaged in Ladbroke Grove.
Travellers, including Countdown star Rachel Riley and singer James Blunt, were among house stuck.
Elizabeth line, Great Western Railway and Heathrow Express trains were all affected, with some passengers trapped for more than three hours with no access to toilets.
Multiple rail system faults and damaged rails had caused problems on Paddington services in the weeks before the incident.
Ms Handforth had been in the role for three-and-a-half years. Before joining Network Rail, she was chief executive officer for the Port of Aberdeen.
Ms Handforth was paid a £330,000 salary and commuted to work from Aberdeen.
