Rail workers were “forced” to take action after a train travelling 72mph hurtled towards them in Dundee.
The Rail Accident Investigation Branch (RAIB) has launched a probe into the near miss on July 10 in which a generator was struck as workers fled to safety.
A team of workers were on the small rail bridge on Riverside Avenue around 12.30am when the incident happened.
The RAIB said workers only had “very little space” to move into to avoid being hit.
A statement from investigators read: “A train travelling at 72 mph approached a gang working on a bridge approaching Dundee station.
“Two workers who were working on the bridge at the time were forced to move clear of the train with very little space available between the train and parapet. The train also struck a portable generator which had been left on the line.
“We have undertaken a preliminary examination into the circumstances surrounding this incident. Having assessed the evidence which has been gathered to date, we have decided to publish a safety digest.
“The safety digest will be made available on our website in the next few weeks.”
