The man , who was in his 40s but not named by police , needed surgery after being dragged onto the track at Huntingdon in February last year.

A report by the RAIB said the man had been standing on the edge of a platform after waving a passenger off when he was hurt.

Investigators said the train was operated by the driver and had no additional staff.
