The extra train, new stations and
additional track will also need to be maintained.

Is that really a noticeable percentage of 28 million?

Why do you think this particular stretch of line will pay its operating
costs from revenue, when the system taken as a whole doesn't?

[Tube fares are about £1.6BN, operating costs about £2.4BN, capital
costs on top of that].
