Signaller 'complied with rules when advising Stonehaven train driver' before crashThe train derailed in Aberdeenshire in August 2020 after it hit a pile of gravel washed on to the track by heavy rain. A signaller who instructed a train driver to go at normal speed just moments before it crashed into a landslip in Aberdeenshire "complied entirely" with the rules in place at the time, an inquiry has heard. ‌Three of the nine people abord the train at the time - train driver Brett McCullough, 45; conductor Donald Dinnie, 58; and passenger Christopher Stuchbury, 62 - were killed. In his evidence, Paul Ashton, who had been head of operations, principles and standards at the time of the crash, said Network Rail has since made substantial changes. A criminal prosecution saw Network Rail fined £6.7 million in 2023 after it admitted health and safety failings over the crash.
