EXTRA rail carriages are being laid on to ferry Town fans to Old Trafford on Sunday.
Rail bosses also hope to get some extra trains to cope with demand.
But the message from rail companies ahead of the big play-off game against Peterborough is: Allow plenty of time for the journey.
No more pre-bookings will be allowed and there are expected to be long queues at the railway stations before and after the match.
First TransPennine Express (FTPE), which manages Huddersfield Railway Station and operates services to and from Manchester, and Northern Rail are anticipating large numbers of Terriers’ fans to travel to the huge end of season finale.
Town have sold over 30,000 tickets for the showcase game and thousands are expected to follow the Terriers by train.
FTPE operates three trains an hour between Huddersfield and Manchester Piccadilly, leaving at 01, 17 and 28 minutes past the hour. Journey times to Manchester Piccadilly are approximately 35 minutes.
Northern Rail has services to Manchester Victoria, again with three an hour.
Edith Rodgers, FTPE’s Customer Services Director, said: “Trains between Huddersfield and Manchester Piccadilly are likely to be very busy and we would encourage fans to travel as early as possible to ensure they are not disappointed.
“We are making every effort to make extra carriages available and we want to carry as many fans as possible but we only have a limited number of trains available to us. We are also trying to bring in extra trains from elsewhere on the network.
“We would ask for fans to understand this and be patient with us.”
Northern Rail will also be operating services from Huddersfield to Manchester Victoria, where customers can connect on to the Manchester Metrolink trams for journeys to Old Trafford.
British Transport Police will be patrolling the stations and will be travelling on certain services to ensure everyone is kept safe and enjoys their day and trip to the Theatre of Dreams.
There will be a queuing system into Huddersfield railway station and on to the trains, which will be operated on a first come first served basis.
Reservations are no longer available although those already booked will be honoured where possible, with passengers moved to the front of the queue.
John Stubbs, from British Transport Police said: “Sunday is going to be a very busy day. We want all Huddersfield Town fans to enjoy themselves and hopefully celebrate their promotion to the Championship.
“The trains have a limited capacity and we are advising fans to travel early and utilise the services throughout the day.”
Returning from Manchester is also likely to be busy and passengers are again asked to stagger their return journeys.
