Tiny boilers for a revolutionary tramway

The Saint-Romain-de-Colbosc tramway used three Serpollet steam railcars for its service starting in May 1896. This system relied on generators made of flattened tubes coiled in a spiral, where injected water instantly turned into superheated steam upon contact with the flames. Despite this revolutionary process and a refined interior offering 32 seats, the Company had to part with them quickly because the vehicles did not adapt to the difficult profile of the line.
