Same here - IIRC they don't fit through the Picc tunnels, so if they
need to go to Acton Works, they'll have to go by road. This
effectively makes the Picc-Vic connections at Finsbury Park
redundant (except maybe for engineering trains?). I don't have a
specific reference off the top of my head though, so I could be
wrong.

They won't ever go to Acton Works, by road or otherwise. All
maintenance will be at Northumberland Park; anything that can't be
done at Northumberland Park will be done at Derby.

Engineering trains will continue to use the Picc-Vic connections at
Finsbury Park.

Is it that they actually don't fit, or just that it would be so
expensive and time-consuming to confirm whether they do that it isn't
worth it?

AIUI "they" (presumably Metronet) ran a 1967 Stock with bits of foam
stuck to it through the Picc to see if it did. Either it didn't, or
the decision was made to deliver by road anyway.

(why wasn't Northumberland Park connected to the GEML? Even in 1967
that would surely have been a more sensible way to deliver the trains
than via half the Underground network...?)

Northumberland Park depot was in 1967 connected to the Lea Valley line
that runs alongside it (not the GEML many miles away).

Somebody decided it would be a good idea to remove the connection after
the 1967TS stock had been delivered.
