Had a quick look at RTT for the last couple of days and it does look like EMR have pulled themselves together and run all the IC (and Connect) trains they had said they would with no obvious cancellations at the London end and I didn't spot any very late running either. Connect seems to be all back to 8 cars now too.
This does hopefully bode well for the slightly stepped up timetable next week which - for instance - restores 1732 and 1932 London-Sheffield, that were deleted.
However (and I think I may have already made this point), the sudden improvement also correlates quite closely with the arrival of cooler weather. If I were a very cynical railway manager, and I knew a lot of issues were heat-related, I might also feel quite confident about improvements as summer turns to autumn without actually having changed any of the basics.
So the obvious question that perhaps the railway journalists and politicians on the route should be posing to EMR (and perhaps Lord Hendy) is what assurances they are prepared to give that the the train service will not drop off a cliff again next summer?
