A male in his 30s was attacked onboard a Manchester Piccadilly to Milton Keynes service at about 11.30pm on Friday, November 3.
The victim left his seat to use the toilet when he was approached by a man who punched him in the face. He was then pulled to the floor and repeatedly punched and kicked by a number of people.
When the train stopped at Wolverhampton, the victim was able to press the exit button and when the door opened, pulled himself out of the train and onto Platform Three where he called for help, while still being restrained and assaulted.
Those responsible for the assault attempted to regain entry to the train but then left the station at Wolverhampton.
The victim suffered significant injuries to his back.
