That does seem a bit crazy though given that, in the scheme of things, Newbury to Bedwyn is tiny compared to the rest of the GW electrification, so surely the percentage increase in total cost would be presumably very small indeed. You have a long-standing through service from London, surely the logical thing is to electrify the whole of the route covered by the service rather than electrifying part of it and making the route dependent on the availability of IETs which arguably are better deployed elsewhere (and which has led to the very problem under discussion)?I don't know when through services between London and Bedwyn came in, but they were there in 1996, so quite a while. Granted Bedwyn itself is pretty small, but Hungerford is a reasonable sized town.Probably the spiralling costs of GWML electrification more than anything else.
It would have been a natural fit for the same 387 pool which does all the other Thames Valley locals and semi-fasts.
The lack of electrification to Oxford is easier to justify as a high proportion of services to Oxford carry on from there onto non-electrified track.
