(Video from the Rail Accident Investigation Branch)
A train on the Norwich to Cromer line in Norfolk came within feet of crashing into two cars on a level crossing after the barriers lifted too early.
Video footage from the train cab shows how the two cars crossed the tracks less than half a second ahead the train speeding towards them at 40 mph.
A rail accident investigation into the near miss at New Rackheath near Norwich in November 2019 blamed leaves on the tracks which meant signalling equipment failed to detect the exact position of the train and raised level crossing barriers early.
