Then you would be the subject of an employment tribunal and out of a job.
The people in control have the bigger picture to those of us on the ground. There may have been other reasons why they needed that unit out the way. Just because you didn't see the reasons why doesn't mean they don't exist.
There's no bigger picture than providing the timetabled service to the paying passengers and prioritising services for the greatest passenger loadings. That means getting the trains to run on time in the first place and after that having appropriate recovery measures which inconvenience the fewest paying passengers. I'm concerned that the "people in control" have KPIs centered around reducing delay minutes and recovery of the service at turnaround points. This will naturally lead to obsession with "getting the train to it's terminus so it can come back in the opposite direction". This is fundamentally flawed, because it takes no account of the hundreds (perhaps thousands) of passengers relying on the delayed service to get them to intermediate calling points and fixates on the relatively few people coming back into London at the tail end of the peak.
Think about it, at Thameslink service heading north from London terminating at Peterborough/Cambridge/Bedford at 1800hrs takes about 1 hr 10 mins to run from Blackfriars to Bedford. So it won't be heading back into London until after 1910hrs at the earliest and most likely has a 20 minute turnaround at Bedford. So it's likely to be forming a 1930hrs (or later) service towards London. Trust me, that train will be leaving Bedford with a handful of passengers and won't start to pick up greater numbers until it's south of Luton, which is more than half an hour from Bedford. By my estimate, that's getting on for 2000hrs. That isn't a peak commuting time, or a peak journey time for most people.
I suspect the same metrics apply to the other northern termini for Thameslink, who, in their infinite wisdom, are happy to run trains northbound during the evening peaks
NON STOP from St Pancras to Bedford or non-calling at Leagrave, Harlington and Flitwick, often with the calling pattern being further amended en route. Last Monday evening the 1727 Blackfriars to Bedford, which is usually fast to St Albans then Harpenden, Luton, Flitwick & Bedford, ran non-stop from St Pancras to Bedford because it was
EIGHT minutes late at Blackfriars. This is usually a busy train, but I suspect ran largely empty from St Pancras as most passengers had to cram onto the following 1742 (express) and 1747. Both these trains were delayed because of the extra passengers trying to board at Farringdon and St Pancras.
So, by running their train set at 1:1 scale, Thameslink possibly got the delayed train to Bedford closer to time, mostly empty and at the inconvenience of three trainloads of passengers.
And for the benefit of "ComUtor", the delay on the 1727 was because of slippery rail conditions, i.e. NR doesn't cut trees back anymore to save the "fwuffy skwiwwells". It wasn't due to a failed train (TOC incompetent maintenance regime) or a UFO on the line "Damn you Vader!".
