So you can't/won't answer that question about what was said by officialdom about the scope of the project. This is a rail specific forum so those claiming that the scheme has fallen short of what was promised shpould know the answer. Having seen acres of posts about how terrible pacers and sprinters are, their unreliability, the pollution and noise that they create for anybody nearby, and the dire shortage of DMUs in the north, an electrified line on quite a large scale will be seen as quite an improvement. Those who previously had to put up with the services of the day won't have any problems seeing the improvements. Come back in a year, and providing the teething problems aren't that significant, those complaining about having to use buses during the works will just be getting on with their lives.
So your measure of whether a scheme is worthwhile or not is if the people inconvenienced are still moaning in 1 year’s time. Also electrification has nothing to do with Pacer withdrawal.
If you want a sensible discussion which doesn’t include referring to the DfT’s project deliverables then the way it has been sold to the public is faster, quieter, greener journeys.
The journeys won’t be faster, or at least not to any degree where they will either notice or where it makes a difference to their lives. They won’t be quieter as the loss of the drone of the diesel engine, which most people can block out anyway, will be more than made up with the incessant auto announcements on the 319s. That just leaves greener and if they drove during the blockade how many journeys will they have to make to compensate for that?
Is a 1 minute improvement all that's been achieved?
It depends on where you are going. As an example the current 06:35 Blackpool North – Manchester Airport is replaced with a 06:38 Blackpool North – Manchester Airport EMU service in the new timetable. The calling pattern between Blackpool and Preston is the same.
The journey time to Preston is 1 minute quicker but 2 minutes slower to Manchester. The route between Preston and Manchester has changed but that is of no interest to passengers, just the journey time.
