Network Rail failed to notice that works by Carillion on Aberdeen to Glasgow line did not match the design
A drainage system wrongly built by Carillion and unchecked by Network Rail led to the Stonehaven train crash, investigators have found, when a Scotrail train hit debris washed by rain on to the railway track.
Three people died on 12 August 2020 in the worst fatal event on the UK railways in 18 years, when the passenger train from Aberdeen to Glasgow derailed at Carmont, near Stonehaven, after heavy rainfall.
