The worst thing about all this is GN was a pretty reliable railway just a few years ago. Whilst it was fragile in that things could fall apart quickly once something comparatively small went wrong, nonetheless a lot of effort had been put in by National Express to get the basics right, such that most of the time things didn't go wrong and the service generally ran on time. First Capital Connect continued this, and whilst they weren't to everyone's taste they did at least maintain a good service operationally, increased capacity, and had a good flow of information such that when disruption did happen people generally knew what was going on.
Since the 2000s this railway *should* have got even better - with additional platforms at Peterborough and Cambridge, the Hitchin flyover, extra tracks available in the Alexandra Palace/Finsbury Park area, an extra platform at King's Cross, extra trains, and more reliable and quicker 387s replacing the 317s/321s. Instead, thanks to the Thameslink Programme and its associated TSGN franchise, this dependable rail service has been totally destroyed, and I just can't see it recovering to anything like the same level of dependability unless the whole programme is looked at again.
I hear there have been issues at High Barnet with the station car park filling up unusually early, I wonder why that is?!
