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].

How does that answer my question?

It doesn't, but previous answers did: the link is projected to make a
modest operating surplus, which will go towards servicing the capital cost;
if it ever repays the capital, the surplus will be shared between HHC and
TfL. It is estimated to have a relatively low B/C ratio, just enough to be
worth doing, but not enough to have made it a high priority.
