There's a bit of a difference between telling people times are changing and the reality of the railway taking an axe to a well-established service pattern - then advising people that their exciting new reality in the peak is to get on an overcrowded XC train, where they will be lucky to get a bit of a seat to perch on, and having to change trains half-way through what has, in the main for over a decade, been a direct journey on a train with adequate seating capacity.
And no one travelling from the Cotswold Line or Oxford into Reading will have to change their habits at all - as everything will still stop there.
It is plain enough looking at the difference between the draft timetables and what emerged at the last minute that this is all about what is convenient for Network Rail and GWR's operational needs, with what is convenient for passengers not considered. Even those getting from London to Oxford a few minutes quicker than on a train calling at Reading are unlikely to be overcome with gratitude to GWR.
People wanting to get from Reading to Oxford have, not surprisingly given the time penalty, never been that keen on using trains that stop at all the intermediate stations, which is what the 387s do out to Didcot now and would continue to do even if they could get to Oxford - and are irrelevant in the context of the loss of afternoon and early evening peak through services between Reading and the Cotswold Line, which is the nub of the matter for those living in places beyond Oxford.
