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?

Shepherd's Bush (Central Line) with its Siamese twin platform layout.

Notting Hill Gate for the layout with one Central Line track above
the other. (There are a few other stations like that, but this one is
also an interchange, thus more interesting.)

Also on the Central Line, ride from Shepherd's Bush to East Acton and
back, after reading the history of that section, and imagine how the
layout used to be at Wood Lane and the old junction between White City
and East Acton.

Where's that pedestrian tunnel that runs through the exposed remains of a
tunneling shield? Waterloo (Waterloo & City)?
