But LO trains have very relaxed schedules, and often wait longer than
necessary at stops, thus helping achieve their very good punctuality. LU
trains, with their lack of published schedules, don't have to do this.

Actually, they do have a timetable, it's just that they don't make a song
and dance about it to the public.

eg: https://www.tfl.gov.uk/cdn/static/cm...tropolitan.pdf

That's why I used the word "public".

I said "public", you said "published" (tomato/potato)

But the Amersham and Chesham branches
are infrequent enough that the scheduled times do matter; I doubt that many
people worry about the schedules on the Uxbridge and Watford branches,
except in the very early mornings and late at night.

But the trains still have a schedule to keep to, and can just as easily
have to wait at a station for the recovery time to catch up.
