If you were HAL you would have wanted guarantees about the revenue due
to you so you could pay off the debt incurred in constructing the
tunnels into Heathrow. I believe the agreement runs to 2023 when the
debt should be clear. Goodness knows what happens then.

I suspect that Heathrow will come properly "into the Zones", but HEx
will be allowed to run trains through the core, at least as far as
docklands (or Stratford if that's a more logical place to reverse them).

I can't see that happening at all. I also would not be surprised if
there are legal restrictions in the Crossrail agreements that prevent
services other than those franchised by TfL from running through the
tunnels.

HEx amd a £230m contribution towards Crossrail, and are letting
Crossrail use "their" platforms and access vis airport junction. I would
not find it surprising if some concessions went in the other direction
(and they'd be paying Crossrail track access charges too).

I'd also found this article:

24 March 2011

Airport operator BAA chief executive Colin Matthews this week
threw his weight behind plans to run Heathrow Express services
through Crossrail’s central London tunnels.

He said he was backing the idea of extending the dedicated
Heathrow services east from their current Paddington terminus
and into the tunnels being constructed for Crossrail, "with
maximum enthusiasm".

The plan was outlined by Network Rail in its London and the
South East route utilisation study late last year.
Network Rail believes this would also remove the need for many
passengers travelling between Heathrow and central London to
change trains at Paddington.

BAA had previously campaigned against calls to dovetail Heathrow
Express with Crossrail. It objected to the legislation that
authorised the line, fearing that the Department for Transport
could take over the Express service.

However, Matthews told a Westminster Energy, Environment &
Transport Forum event last week that BAA now backs the idea.

"The opportunity of Heathrow Express going forward with
Crossrail, to make sure you can get from Heathrow not just to
Paddington but to other destinations in London, is going to be
great," he said.
