AIUI, there won't be a huge amount of track-sharing. Crossrail gets
exclusive use of the slow tracks on the GWML, although it'll share with
HEx from Airport Junction to Heathrow Central.

From the opening of the committee on Jan 2006:
"On the Great Western main line Crossrail will share the slow or so-
called relief lines with freight and complementary passenger services
to Reading. The intercity services and Heathrow will continue to use
the fast or main lines during normal operation."

I don't think things have changed. The other services are all stops
Reading-Slough, plus the Reading-Paddington semi-fast is meant to have
same-platform interchange at Ealing Broadway, which means relief
lines.
