I'm trying to compile a list of interesting things to go see on the
"tube" on a day trip. Engineering mainly, like the crossover at the end
of the Oxford St Bakerloo, the scale of Canary Wharf and the tunnel out
of Bank-DLR. What others can the team suggest?

Step-plate junction and being able to see across to the other platform
at the southern end of the Bakerloo at Piccadilly Circus.

Wartime trackside flood-gates at both ends of each Northern & Bakerloo
platform tunnel at Embankment and Waterloo (Bakerloo ones are more
"visible").

More visible closed stations between Kentish Town & Camden Town (South
Kentish Town), TCR & Holborn (British Museum), and Caledonian Road &
Kings Cross (York Road - well-lit emergency exit). Also surface
building of the same (bar) Mritish Museum) and a few others (e.g.
Brompton Road & Down Street - in need of a blue plaque?!).

Wartime Deep Level Shelter entrances/blockhouses.

"Fake" house at Leinster Gardens and District Line in cutting at rear
(between Bayswater & Paddington).

Memorial plaques at Balham, Bethnal Green, Bounds Green (WW2) & Kings
Cross (the fire).

Disused Wood Lane station platform northbound between Shepherd's Bush
& White City.
