Electric to Windermere isn't going to happen - no wires.Manchester to Windermere should be hourly (and electric) - with Liverpool possibly taking on Barrow and Morecambe on alternate services? But where does that leave Scotland, and we don't even have Liverpool - WCML - Edinburgh in contention.
Makes me think that the whole Wigan-Cumbria trunk could see even more service. Possibly an hourly from Manchester to each Scottish city.
And with the 2tph to London, we could really speed up the prime London-Glasgow hourlies to start stoking 4h10-4h20 standard timings, in advance of HS2.
The Barrows are meant to be hourly from Man Airport, with some separating at Preston/Lancaster to run half on to Windermere (I think).
Liverpool will get a direct TPE service to Edinburgh via York, and us intended change away via Preston, which I think is enough unless there's a sharp increase in demand.
I'm all for increasing capacity, and competition, north of Wigan on the WCML, but there's 3 journey opportunities per hour as it is. I'd rather sort out the Wigan-Warrington-Crewe fiasco first.
