The 27-year-old man was waiting for a train at Harringey Green Lanes station when one man began attacking him on May 6 at 11am.
Another man joined him and the pair struck him with weapons, believed to be wooden poles.
The man was left needing hospital treatment for a cut to his forehead.
Police have released CCTV images of two men they think will be able to assist them with their investigation
Detective Constable Graeme Knox said: “I’m keen to speak to anyone who thinks they might recognise the men pictured or who was at the station at the time and witnessed the incident. Violence of this kind is completely unacceptable and will not be tolerated on the rail network.”
A 27-year-old man, of Hackney, was arrested on May 6 in connection to the attack on suspicion of affray and has since been released on police bail until July 9.
