I wonder where all those Met tubes are going, then? Not the
Uxbridges, not the Amershams, but the ones with "Watford" on the
front...

They're not tubes - they are cut-and-cover ("tube" traditionally describes
the trains using the deep-level bored tube lines, not those like the Met and
District built by scooping out a trough and subsequently covering it up).

Hmmm - TfL now describes all of them as "The Tube"..... (something about
when you're in a hole, stop digging?)
