Those Froggies don't half like wordy titles, hey? ... the Vivarais metre-gauge system.
I've never seen the Vivarais, whose enthusiast support group seems to have major difficulties in recent years, and I'm not sure if the main part is running. Anyway, shortly after the enthusiast reopening, about 1971, the BBC (of all organisations) decided to make a comedy TV series, in English, of the classic French book "Clochemerle" by Gabriel Chevalier (repeated in the early 1990s), and the village they chose was on the Vivarais and their Mallet tank and vintage stock can be seen in several shots, and takes centre stage in a couple of them. Hands up if you recall the TV series (very well done and humorous, and now finally available on DVD).
Anyway, the intermediate station, and the village, they chose for the location scenes, was (pause for breath)
Colombier-le-Vieux - St. Barthélémy-le-Plain
And yes, the whole lot does appear on the station name board. 39 characters. A worthy challenger to Llanfair PG.
