Been trying to remember the number of the London Transport bus which did this route; was it 335 Amersham to Hemel Hempstead? It alternated with the Rover Bus service although the Rover went along Whelpley Hill to the caravan site and back which the LT service didn't. It wasn't the 336; this was Chesham to Watford in special 'low' double deckers as there were one or two bridges on the route which weren't high enough for 'standard' RTs.
Corrections thanks to OUAQUKGF Ops for sending me a link about London Transport:
It was service 316 Amersham to Hemel, and the special low double deckers were RLH.
