In any case this thread started discussing the situation where the normal
Piccadilly Line option is not available.

What they should do is put on extra "Connect" trains, and accept TfL
tickets. HEx is a red herring.

No paths for extra Connect trains (either on the GWML, or in the
Heathrow tunnels).

So how is Crossrail going to work then? (And we are talking about
Sundays).

They are rebuilding Airport Junction. It was originally built for HEx
to/from the fast ("main") lines of the GMWL, and the access to the slow
("relief") lines for Connect was cobbled together on the cheap. It
involves down Connect trains running on the up HEx line on the flyover,
and up Connect trains running across the down Relief line on the level.
It's being replaced by a proper grade-separated junction with access
to/from both main and relief lines.

Quite what will happen at the airport isn't clear. Crossrail planning
has assumed 4 tph Crossrail and 4 tph HEx. Crossrail maps have always
just shown "Heathrow Airport". At one time, the plan was to replace
Connect and terminate at T4, which never seemed very likely. How can
Crossrail not serve T5 when it's the main terminal for the main British
airline? The map on the Crossrail website that shows TBM progress has
the Heathrow destination shown as "Heathrow Central".
