New Rackheath On 24 November 2019, unit 755416 was approaching a
level crossing at
New Rackheath, in Norfolk, at when the barriers lifted as the train was from the crossing; cars started crossing in front of the train. The driver of 755416 initiated an emergency brake application, but the train was unable to stop until it was beyond the level crossing. A collision was avoided by less than half a second. The cause of the incident was contamination of the track interfering with detection of the train by track circuits. The equipment had been set to open the crossing 16 seconds after a loss of signal. The equipment operating the level crossing was reset to open the level crossing 99 seconds after a loss of signal and computer program on the train was rewritten to remove a ten-second delay in the application of sand in the event of wheelslide.
