Yeah, and since TfL have no shareholders, the money usually earmarked for those shareholders goes back in to TfL's account to make small improvements like deep cleaning of stations that other operators just won't do.
Plus, I'm sure TfL have considerable economies of scale across all their operations: admin, cleaners, maintenance, signage, ticketing machines, websites, social media. I'm sure there's a huge amount of pooling that goes on across their various services which likely saves a lot of money. Although I know Govia does a similar things with GN/TL/SE/SN, it's a much smaller operation overall with many more things contracted out to other companies who want to make a profit for their piece of the pie too.
Also, just putting a route on the tube map usually corresponds with a huge increase in ridership as we've seen with the NLL, ELL and Lea Valley Overground lines, and more fares money as a result.
I don’t get what benefits people think TFL will bring.
New trains = already coming on stream.
Station staffing = many stations already staffed first to last.
Gates = many stations already have these.
More services = route already running near capacity.
Longer trains = trains already at maximum unless they run a few longer services to KX, but with what rolling stock?
Oyster = the London part of the route already has it.
So we’re down to better reliability - which *shouldn’t* need TFL to deliver, gormless TFL staff hanging around everywhere, and some station enhancements - for stations which let’s be honest are in most cases perfectly fit for purpose today.
As regards ridership, the expression be careful what one wishes for springs to mind. So the route is already busy at times - do users *really* want it to become busier when capacity is highly limited by the infrastructure?
Then consider the inefficiencies of having a small operator running a small subset of services, or being bolted to another LO concession and thus lost in a larger monolith?
TFL was able to be transformational on some of its existing routes because of the investment opportunities. Much of this doesn’t apply to the GN inners. They’re quite content to plod up and down like they’ve been doing for the last four decades, lest someone sorts out the current reliability issues.
Remember also that TFL is financially broke at the moment, and may very well get more broke over the next couple of years with Crossrail being delayed, the SSR resignalling slipping to the right, and political government versus mayor games going on - perhaps a Conservative government happy to let a Labour mayor take the rap for issues. Will they actually be able to afford the orange paint?
