We are a group of 4 wanting to travel from Dumfries to Bristol on Aug 26. Is this a high speed train? Are advance reservations advised? Thank you very much for your time.
Minimum of 2 changes of train at Carlisle & Birmingham / Wolverhampton for this trip; the first train is a local. Your date of travel is a bank holiday so the really cheap tickets if there were any are long gone but reservations are probably a good idea on the second two trains because of the holiday. Can currently book an advance single for £80 each.
For the actual train connections that day see http://ojp.nationalrail.co.uk/service/timesandfares/DMF/BRI/260813/0800/dep I started the query at 8 am, you can change that. The trains will be a combination. The train from Carlisle to Wolverhampton is a 125 mph Virgin Pendolino. The train from Dumfries is a slow commuter. The train from Birmingham will be a diesel Cross Country train which, depending on which type runs that day will either be capable of 125 or 110 mph. The track, though, won't generally support that speed on that route. I don't understand why the computer is having you change at Wolverhampton and Birmingham since the train from Edinburgh will stop at Birmingham after its stop at Wolverhampton, on its way to London. Be aware that there are 2 large stations at Bristol. The main one is Bristol Temple Meads, and there is Bristol Parkway. You should be careful to specify which you require when you get your tickets.
