A fatal train derailment near Stonehaven, Aberdeenshire, that killed three people in August 2020 could have been avoided if a drainage system had been built according to its design, a fatal accident inquiry has concluded.
Drain construction flaws identified
Sheriff Lesley Johnson found that construction firm Carillion deviated from the design in several respects when building the drain in 2011 and 2012. Issues included piping, materials, and an added bund that prevented proper function. The drain could not handle intense rainfall on 12 August 2020, washing debris onto the line.
Network Rail and Carillion failures
The sheriff also ruled that Network Rail failed to ensure the drain was constructed properly and did not obtain "as built" drawings from Carillion. Carillion went into liquidation in 2018.
Criminal prosecution and fines
In 2023, Network Rail was fined £6.7 million after admitting health and safety failings. The train, traveling at 73 mph, hit washout debris, derailed and struck a bridge parapet, scattering vehicles.
Industry responses and safety improvements
Network Rail Scotland managing director Liam Sumpter said significant changes have been made to manage severe weather risk. ScotRail, unions RMT and Aslef, and the Crown Office all emphasized safety improvements and condolences. The Rail Accident Investigation Branch made 20 recommendations, most implemented.
