According to police, attempts to restrain the man failed so they used a Taser.
A spokesman said: "When police arrived the man had boarded a train which had been held at the station. Officers boarded the train and made their way through the carriages to the male suspect who had his hands in his pockets.
"The suspect moved forward towards the officers whilst shouting and refused to remove his hands from his pockets. Attempts by the officers to physically restrain him failed so they deployed Taser.
"The man was Tasered a number of times but this seemed to have no effect. Eventually officers were able to physically restrain the man and he was removed from the train and into the custody of British Transport Police."
