There are regular trains to and from both Victoria and Piccadilly to Horwich Parkway at least every half hour. The station is about 500 metres from the stadium.
But will there be a queue?
Yes - will I be able get on the 1724 to Preston
Easily. Never been any queues for the services back to Preston when i've been to The Reebok.
Even the queues back to Manchester aren't that bad.
