Apparently a lot are heading up to the liverpool & manchester area. Curiously
they're removing their 3rd rail shoegear which means they can't run on the
merseyrail system which seems a bit shortsighted to me. You'd think the more
flexibility the better.

It's possible that the shoegear is out of gauge for somewhere up there.
I think that's why the 365s had it removed when moved from south of the
river to WAGN-as-was.

Possibly. Though you'd think NR would keep most of the network in gauge for
3rd rail simply because there may well be a class 92 or 73 trundling along
there one day.

Don't 92s have/had third rail shoes which can be lifted above the normal
level when not in use, for precisely this reason.

The cock and valve diagram for 92s
[https://www.flickr.com/photos/99279135@N05/16825734107] seems to
confirm that.
73s also do that as well as 377s
[https://en.wikipedia.org/wiki/British_Rail_Class_377]
also 350/1s :-
