It isn't too difficult to find blogs of individuals that were opposed to Bedwyn electrification not so much on aesthetic grounds but a feeling that it would increase road traffic to the station (& associated parking problems) for the improved service. No indication this was related at all to the Passenger Group though.
I have bolded that element to say "you don't know how right you are" ... and I am having to be very careful indeed how I write. The longer established moderators will know exactly where I am coming from. Are you sure that the blogs you found
were from
different individuals? Parking has been a massive controversy and has spilled over into the whole "do we want better trains because it will bring more people?" question.
BTPG have been in, perhaps, a similar situation to the people who want electrification thorough Bath - supportive of course, but anxious for their support to be in such a way that it doesn't generate a massive backlash. In spite of Steve's wording, written for the local audience in Bedwyn, there was no "opposition to electrification" outside one or two individuals.
