Purely by coincidence, reactionary delays have been on an upward trajectory in the past five years, despite the number of delay incidents falling slightly.
I wouldn't say its a coincidence. Historical delay incidents have been almost designed out. Delays are slowly diagrammed out with each timetable change and TOC's have been a bit more clever with how the delays are calculated. Didn't you say in another thread that Cancellations done by the previous day do not count towards PPM ? Am I correct in thinking that Major disruption caused by certain incidents are also removed from PPM ? (that's what the posters say)
Add in Right time railway and how some diagrams have been changed to STP and regular delay minutes compensated for.
Better pathways on both sides (NR/TOC) also help to remove delay minutes on a more permanent basis.
I have also been told specifically to reword delay reporting because it switched attribution to NR and not the TOC.
Reactionary delays will always be there because you just cannot plan for every eventuality.
Thanks to the tenacity of Drivers on TOC's such as Thameslink TOC's being reliant on Rest Day working has become common knowledge and they have
almost been forced to recruit and increase SP turns. I know at my TOC that SP turns have been increased over the years and there was a recent increase of bank holiday SP turns (can't remember the %)
As to the situation with training etc at Thameslink. Wasn't a Director removed from her post a few years back because of the failure when the Sevenoaks route was reintroduced to FCC. Training was left to the last minute and SE had to cover lots of the work because of the training shortcomings. I'm not going to place the current crisis directly at GTR Management because I see the bigger picture.
FYI like the above poster I have worked in a previous job where your sitting on the phone ringing round staff and not getting any cover. Staff would often ring in with less than an hour before they were due to start. Sometimes, despite all your best intentions, things can be beyond your control.
