I think you'll find that service recovery and disruption has been going on longer than "May 18"! It wasn't all rosy and good times just because trains terminated at Kings Cross no doubt.
Yes, it really was. There was a long period during later WAGN and the whole FCC tenure when you could set your watch by the GN service. Well, Mondays to Fridays anyway. Essentially, you didn’t need to check what the service was doing before leaving the house.
Much as these two operators were a bit maligned, they really did know how to get the basics right. WAGN improved massively under National Express, and FCC kept it up.
RTT has the train
2L through Hitchin also, not 1 early. It was back to booked time at Stevenage which is almost the perfect amendment to get back to right time running; no more, no less.
It wasn’t 2L at Hitchin, it passed pretty much on time, I know because I was on the platform and saw it come past.
My point is that there was no need to amend it to get it back to RT. There’s 3 minutes of allowance between Hitchin and St Pancras, and a bit of extra station dwell too. So the amendment made was too aggressive, and inconvenienced a lot of people completely unnecessarily (and will have potentially cost some delay repay).
There are a lot of "ifs" in your statement there, how do you know crewing arrangements didn't allow? Doing nothing leads to knock on impacts, especially if you are running trains late through a congested core, and then any conflicts for example through East Croydon. There's a lot to consider. You wouldn't want to turn a train at Crawley, although Three Bridges might be possible. Also less busy stations might also be less well served, so even though there are fewer passengers, it may well be a longer wait. I'm not saying it does, but again another consideration. Also if running fast, this is effectively pointless if you basically end up behing a slow stopping service, so location has to be considered.
Service controllers look at a range of options before making decisions and have to balance multiple competing demands including turnaround times, platform recoccupancy, crew risks etc. It's all much more complex even if I can understand people asking "why did they do it like that". And yes decisions are easy to make in hindsight and not every single one will be perfect. Even when done with the right intentions, sometimes it works and sometimes there's an unforseen clash or issue which means that the plan doesn't work as intended. Especially on busy sections of line.
"Doing nothing and let it run" is exactly how disruption continues for hours on end - with more passengers inconvenienced - if you make no interventions
This brings us back to the whole thing of what is the point of running a service in the first place, if it isn’t to move people from A to B. Really, the least worst outcome once the train was initially delayed, is to get it to Horsham just in time for it to have a quick turnround and return close to or at right time.
This just feels like someone looked at the fact that it was going to leave Peterborough late, worked out that pulling a few stops would get it on time by Stevenage, and that’s about all the thought that went into it. If so, that’s poor decision-making, as it inconvenienced a load of people. A 60-minute gap at five stations, and effectively a 30-minute gap at another. Versus a bit of late running towards Horsham that probably could have been partially made up with some good regulating (which is another thing we seem to lack nowadays).
I would say that's now a) imported performance risk onto Southern services which will lose time and b) you're affecting passenger from Three Bridges - Horsham and Horsham to Three Bridges. Two performance failings, not one.
One late-running train shouldn’t be importing that much risk, and as I said elsewhere 18 minutes of late running ought to have been recoverable to the point where it was able to leave Horsham roughly right time. If the risk of importing delays across the river is so much of an issue, perhaps we shouldn’t have the cross-river services.
