Now how did you come to find it? I trawled the tfl site looking for
just this, but couldn't see any likely-looking links. Obviously I have
a lot to learn about trawling the web.

Yes, it sounds as if you have.
From the TFL site, try the "Tube" or "Rail" tab, then "Maps", or from
the TFL homepage, "Maps", then "Tube maps"?

Thanks. When I looked there for London Connections, either the link
wasn't there or I didn't recognise "Tubes, trams and trains" as being
it.
