Was the old Watford High St to Croxley route ever formerly closed? I
had the feeling that it had its serviced reduced until it could be
replace by a bus.

It was eventually - after some time when it had been reduced to 1 train each
way a day, in the early morning. Then this was bustituted (according to the
timetable, but in practice taxistuted), and eventually formally closed. Even
after formal closure someone reported being able to buy a ticket to Croxley
Green out of a ticket machine somewhere.
