Just a heads up, I've used it a few times and i'd imagine a few people may be unaware ?
But on Tuesday-Weds-Thursday you can get from Brum to london for £2 return on Virgin Trains, and can get from Brum to Edinburgh for £10 return on virgin trains too, a bit nicer than the coach but cheaper than the coach.....Can get about 8 hours in the capital for the price it would cost for going about a mile down the road on a bus !!
They do more routes by train but not many !!
To get the £1 fairs you have to book at midnight though, they go on sale about 45 days prior to the journey by the way !!
