It’s always very amusing when these kind of cynical comments about not recovering the train service because it is more profitable - I tend not to bite but I will today.
As a service controller, for GWR, my job is simply to run as much of the train service as possible, with the resources available to me (fleet/crew/infra), and in line with agreed industry plans for when there is reduced capacity - you cannot fit all of our/MTR/freight timetabled trains in when 2/4 lines are shut through Slough, for example, so there’s cross-industry agreements as to how much we each get to run. I can assure you that I and any of my direct colleagues have less than zero interest in the fiscal elements of train service recovery - in terms both of TOC<>NR (Schedule 8 etc) and TOC<>Customer (Delay Repay). Neither have any bearing whatsoever on what we do. It simply isn’t even on our radar. Moreover we don’t want to know, or have it used as a metric as it’s generally at odds with good train service recovery.
There simply aren’t the crew resources to relieve every late running train at Reading, in a situation like this morning - you might be able to scratch together 2 crews on a good day; but with overtime bans and the like at the moment you’ll be lucky to get 1. Fleet we can generally shuffle the pack around to get RT starts if crew are in the right place.
While the vast majority of what you say is spot on, it can be different.
For instance MTR on the GWML have different contractual obligations regarding who is “at fault” and also determine service status as a TfL mode depending on the level of the disruption. FOCs have external contracts/clients and timeframes to meet, especially intermodal.
Going into severe service disruption also triggers things like ticket acceptance, although that does not always have a cost implication.
Simply put, TOC and NR controllers will try and do what they can to recover the service within the constraints available , but as with anyone there are those who are more proactive, detailed and innovative with their decisions and there may also be pressure from higher levels (e.g. protecting certain service groups even if that is harder to do at the current time).
It is ridiculously cynical and simply wrong though to think that service controllers are even thinking about “ooh well if I cancel this service and don’t alter it then there will be more payment from NR mwhahaha”.
