Blandy mate - think you'll find the trains from Picadilly go to Wigan Wallgate not Wigan North Western - I get the trains to Brum every day and the trains from Picadilly or Victoria go to Wallgate cos they stop at the local station (Hindley).
Probably already mentioned (can't be arsed to trawl through the posts)m but Sky deffo have kickoff as 3.00 - reason they start at 2:45 is that they are showing a live Rangers game from 12.30 then going straight to Wembley for 3.00pm KO.
