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 Farringdon ? The widened lines dive under the Metropolitan lines
to the Northwest and there is Snow Hill Tunnel entrance on the Southeast.
Also, apparently, there are frequent problems with Thameslink trains to keep
you amused.
