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?

How about the big tunnel machine that was used to build the Waterloo and
City line, then abandoned somewhere in the vicinity of Bank station, then
rediscovered when the station was modified to accommodate the DLR, and which
you can now walk through on one of the new connecting corridors.
