Well, thank goodness that's over. My London-Wilmslow-Manchester service was totally messed up for the duration. I can see why they did what they did, but the paths through Manchester are totally unrealistic. Up trains arrived at Eccles on time, to be 15+ minutes late leaving Manchester, and with 8+ minutes of recovery/pathing time included in the schedule. The two occasions I thought to catch the xx.55 from Manchester (which normally starts from Manchester but instead started from Glasgow for the past two weeks), I instead caught the "following" xx.15 Manchester-London from the main station at Piccadilly, then waited on the platform at Stockport for the "following" train (the one which should have been 20 minutes earlier), and didn't even think about trying to find a seat for the Stockport-Wilmslow leg because the diverted trains seemed to be very busy.
Of course, had I a good reason for travelling to Glasgow during the period I might have been happy.
But I hope that Acton Grange Junction is in fine fettle for many years now.
I also hope that, although I can see the logic, I hope this sort of diversion of London-Glasgow services isn't done again. Not that there's an easy alternative solution. Reversing at Liverpool Lime Street might have worked better, though.
