They relate to the tunnelled route SW of Paddington.
Summary:
Proposed new tunnel alignment.
Proposed new Crossrail station at the Vale, Acton.
Proposed new station at Chiswick Business Park, with District, Picc, NLL and
Crossrail services in three directions (Paddington/East London, Richmond/Kingston,
Brentford/Hounslow) However, a Picc/District/NLL station here was ruled out here a
couple of years ago because LU refused to consider stopping Picc trains there.
Proposed new Crossrail station behind Chiswick Village.
Proposed retention of District Line at Gunnersbury, Kew and Richmond.
Proposed closure of Chiswick Park and South Acton due to proximity with new
Chiswick Business Park station.
No need to dig up Chiswick Back Common.

The depressing thing about all of this is the blinkered attitude to
routes, which only attempts to serve traffic to/from central London. If
the base option is built, passengers from Richmond to Heathrow, for
example, would have to change at Paddington. At least now they only have
to go as far as Hammersmith!

West London roads from the North Circular to the M25 are at saturation
for orbital journeys. Acton and Chiswick interchanges on Crossrail would
begin to address this, at a cost of perhaps a couple of minutes on the
radial journey times (which will be a lot quicker than now).

How about 6 Crossrail an hour to Acton (Old Oak), Chiswick Park,
Brentford, Southall, and stations to Slough? That would make lots of new
connections without overburdening the busiest part of the GWML.
