The Trumpton firemen were called to assemble in every episode yet never once put out a fire. it was considered too difficult to create flames, smoke or water from the hoses, due to limitations of the stop-motion animation that was used.
The Trumpton theme tune was resurrected in the early 1990's and released as a 'rave' music E.P. The song was produced and remixed by Urban Hype.
The seemingly idyllic village in the "Endeavour" series 6 episode 3 "Confection", is called "Chigton Green". This name runs together the titles of three animated TV programs for children which were popular on British television in the 1960s - Chigley (1969-) , Trumpton (1967-) and Camberwick Green (1966-) , each of which was set in, and named after, an idyllic English village. Collectively, these 3 series, which all share the same story universe, have since been issued in a 39 episode DVD boxset named as, and are now officially retrospectively formerly known as "The Trumptonshire Trilogy".
Following a series of various corporate takeovers, mergers, and de-mergers, by May 2019, the intellectual property rights to the Trumptonshire Trilogy appear to now be owned by NBCUniversal.
