Simply, I don’t think we should be choosing between the two. Many existing customers, potential new customers, local business, politicians and others have campaigned to reduce journey times across the region and, especially, to/from London. But the timetable isn’t just about journey time, it is also about frequency improvements on many routes. Connections are important and we recognise the new timetable brings some challenges but we are working to address as many, if not all, of these.
It's an issue we're very aware of here in the North Cotswolds: of our four evening peak trains, three of them will skip Reading and run fast to Oxford.
Though this is obviously a nice-to-have for Cotswold-London commuters (and, I guess, makes
GWR▸ more attractive for Oxford passengers vs Chiltern), it's a very big issue for people who commute between the Cotswolds and Reading/other Thames Valley locations. I personally know a handful of people here whose commute will be seriously affected.
I hope GWR will be able to look at this in future timetable revisions and restore the Reading stops to at least one of the services.
