Wales v England: Fans warned over behaviour by police
Police have issued a warning ahead of Saturday's Wales v England football match at the Millennium Stadium.
Cardiff Council advised the 70,000 fans to travel by public transport or coach if possible for the Euro 2012 qualifier.
But a planned taxi drivers' strike has been cancelled.
Police said they are looking forward to welcoming fans but have warned against bad behaviour. An alcohol ban will be in force on trains.
British Transport Police have said that alcohol will not be allowed on any trains arriving into, or departing from, Cardiff Central around the sell-out match at 1500 GMT.
This includes all services from London Paddington, Bristol Temple Meads, Swansea and Carmarthen, and all Valley Lines services.
Insp Stuart Middlemas, of British Transport Police, issued a warning to fans arriving by train.
"Throughout the day, we'll have officers patrolling stations and on board trains between London and Cardiff. They will not tolerate intimidating or anti-social behaviour from those intent on spoiling the day for others."
Arriva Trains Wales will be providing additional trains on match day but long queues are expected and fans are advised to allow extra time for boarding.
The Football Association of Wales (FAW) and Cardiff Council are providing a fans zone for England supporters near City Hall, with big screen, entertainment and pre-match food and drink, with shuttle buses to the park and ride.
Fans travelling by car are advised to plan their journey, arrive early and be aware of road closures.
Cardiff Council is encouraging fans travelling by car to use park and ride services, which will open at 0830GMT, with the last service leaving pick-up points at 1900GMT.
England supporters will sit in the north of the Millennium Stadium and should use parking sites accessed from J29 of the M4.
Wales supporters will sit in the south of the Millennium Stadium and should use parking sites accessed from J33 of the M4.
Cardiff Hackney Carriage Association said a planned strike in the city had been called off after an agreement with Cardiff Council on fares and taxi rank provision.
As well as the football, hundreds of music fans are in the city to see Kylie Minogue in concert at the Motorpoint Arena.
