The man was arrested at the station at around 7.15pm last night (October 23) after the train's crew reported an assault on-board its Glasgow to London service.
British Transport Police met the train as it pulled into Preston station and a man, aged 33 and from the Wirral, was detained by officers.
Officers said they were forced to draw a Taser during the arrest, "due to the man's aggression", but the firearm was not discharged.
