In the December 2009 timetable a train from Swansea was altered to cut out the Didcot and Reading stops (and leaves Swindon ONE whole minute earlier than it did in the May 2009 timetable).
This has made the next two trains from Swindon busier as those travelling to Didcot, Reading and connecting stations have to get those. (The 08:11 which is from WSM, and the 08:28 which is another Swansea). So I think it's a really bad move.

By enabling the serviceto arrive before 9am whilst also being under 3 hours in journey time from start to finish is fantastic
PR▸ and was reported in some local papers in Wales as such. This little bit of positive PR is what is needed to encourage peopel onto rail. If I'm honest as well, Didcot and Reading both have many services to London so speeding up one service that serves South Wales and Bristol Parkway will encourage people to use rail. The other two trains may be busier but this service may benefit a lot more people before from stations west of Reading and Didcot so even though it's only a slight PR win, every little helps in helping to male the railway a viable alternative to the car to both business and leisure travellers
