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 shows that the margin cost of operating the line could well be of the
same order of magnitude as the farebox. In other words, you are seriously
underestimating the additional cost of operating the trains.

TfL apparently expects a modest operational surplus, presumably because
this simple above-ground line is relatively cheap to operate compared to
the deep level Tubes.

A modest surplus is reasonable, but Tim seemed to think it would be the bulk of the £26m.

I think you and I agree that he was ignoring most of the operating costs
(manning the additional train and stations for 2-3 shifts, cleaning and
maintenance of the train, track and stations, electricity, etc). Apart from
at the new stations, won't there also have to be LU staff at the shared NR
stations, Watford Junction and High St?

And I suppose many of the additional fares will be to
Zone 1, and therefore quite expensive.

I hope they don't take such a simplistic view of the extra fares. Quite a
bit of traffic to Z1 will be abstracted from existing stations.

Let's hope not. But obviously there will be net additional fares from zones
7&8, and therefore expensive if to London.
