given that Crossrail will run thru three different signalling systems,

and freight traffic, one can see it will present an operating
challenge.

Three franchises if you count HEx.

True, though the only tracks they'll share are in Heathrow itself, as
Crossrail will use the GW relief lines and HEx is on the mains.

My impression was that they wouldn't be doing much (if any) track
sharing with Greater Anglia between Stratford and Shenfield.

Yes, I think you're right.

There is always the potential for failures on main lines to mean that
signalliers will reroute some trains to slow lines. I understand that
in the longer term it may be necessary to shove HEX on to the local
lines (but I might be wrong on that). Depends entirely on the scale of
FGW services post electrification and catering for growth.

What's really needed for HEX is another pair of lines Airport Jn-Padd.
Wharncliffe Viaduct and Ealing Broadway-West Ealing are the main problems
to achieving that, as far as I can see.

No, it is a typographical error.

Or, as they are known to Great Westernists, the relief lines.

There will still be some in the peaks as Crossrail will still run some
trains into Liverpool St rather than in to the tunnels post 2019.

Will they not be sharing with South Eastern in the Abbey Wood area?

Parallel but separate tracks, surely?
