no, it's because i have some experience from the inside, and see the reality of running this play service for ****heads.
The evidence is clear - trains running with loadings as low as 0%.
Likewise, the actual picture is if one turns up for a train at somewhere like edgware early on a saturday or sunday morning, the carriage is likely to smell of urine, or worse you may be unlucky and find yourself sitting on it.
How do you propose they do this? By having more than 24 hours in a day?
If a piece of equipment develops a fault (for example a defect with a rail, a broken or defective component on a set of points, or a defect with signalling apparatus) it requires staff to go and fix, most probably involving equipment being brought to site, probably followed by a period of testing too. If something goes wrong in the traffic day, the problem will be fixed if the effect on the service is sufficiently serious, or most likely will be dealt with in engineering hours, with likely some kind of limit on the service in the interim, perhaps a platform or siding being out of commission. If something goes wrong from friday morning onwards, there is now no non-disruptive maintenance opportunity until sunday night, thus screwing the weekend day passengers. Unless of course we suspend the precious night tube, but that's not even always a viable option because the number of engineering staff have been slimmed down on friday and saturday nights because it is no longer viable paying people to sit around unable to do any productive work.
There have been plenty of instances where the railway has had to limp through saturday and sunday because something has gone wrong at some point. I can also think of instances where monday morning has been messed up because work has been left until the sunday night and something unexpected has cropped up leading to the work not being finished in time.
But as long as the ****heads get their ****head special train home on friday and saturday nights then all is well.
scrap the whole thing, it's a waste of time and money. We managed perfectly well without it for the first 150+ years of the underground's operation, and i don't remember seeing too many tears when it came in over a year late whilst all the er issues were ironed out. The few days of strikes probably cost london's economy far more than the night tube will ever bring in.
