Yes, that occurred to me after posting. But do Piccadilly line trains
really have to use the side tracks? I realize that doing so can reduce
delays for eastbound passengers getting off at Acton Town, but it
doesn't actually speed up train service much, does it? One train still
has to wait for the other before leaving the station. I suppose the
practice is useful when the Rayners Lane shuttle is running -- but when
that happened to me, the connecting Piccadilly line train across the
platform closed up and pulled out as soon as we pulled in. (It felt
just like home!)

The S Stock (to be used on all non-tube lines) will be low floor, so
this problem goes away by itself once you rebuild all platforms to
tube height.

Also, Silverlink shares trackage with the District line between
Gunnersbury and Richmond and with the Bakerloo line between Queen's Park
and Harrow & Wealdstone.

Don't forget that one day the Bakerloo will take over the whole route
to Watford.

(Silverlink Metro runs Class 313 stock on all of its
electrified routes, right?)

Yes, and the odd 508, which are roughly the same design. High floor.
