At 09:01 hrs on 19 August 2021, a freight train consisting of a class 66 locomotive and 36 container wagons struck a loaded farm trailer at Kisby user worked level crossing, situated near to March, in Cambridgeshire. The train driver applied the train’s emergency brake around 6 seconds before the collision occurred, but the train was still travelling at around 58 mph (93 km/h) when it struck the trailer. As a result of the collision, the trailer parted from the tractor that was pulling it and was then dragged along by the train. The leading axle of the locomotive and an unladen wagon in the middle of the train also derailed. The train ran derailed for around 780 metres before it came to a stop. Both the train and tractor drivers suffered shock following the accident and the train driver was also treated for minor injuries.
