About 500 police officers are tackling football hooliganism on England's rail network on Saturday.
Hooligans have been warned not to travel
They will arrest troublemakers and bar unruly fans from trains, with offenders facing football banning orders.
A total of 19 fixtures, including five Premiership matches where police fear there is the potential for disorder, will see extra patrols.
Police say matches in London involving supporters of Leeds and Hull are of "particular concern".
Andy Trotter, Deputy Chief Constable of British Transport Police (BTP), said: "Rowdy football fans can be a nightmare for other passengers. Even when they are only being boisterous, in the confines of a train or in large groups on stations, they can be very intimidating."
Officers were focusing on the Hull game against Queens Park Rangers, at Loftus Road, west London, because of hostility between fans dating back to a match this summer, when Hull supporters taunted QPR fans over the 7 July bombings, BTP spokesman Simon Lubin said.
He also said there was a history of bitter rivalry between supporters of Leeds and Millwall, who were playing each other on Saturday.
It is the second "Day of Action" run by BTP, the first having taken place on 30 April when officers arrested 10 people after targeting 15 problem games.
In one incident, 20 fans wielding bottles and other weapons clashed at Clapham Junction station in south London.
