The story

The first company to open a line in the region was the Chemin de fer Tavannes-Tramelan, which opened the 1,000 mm (3 ft 3+3⁄8 in) gauge line linking the villages in its name in 1884. This line was extended by the Chemin de fer Tramelan-Les Breuleux-Le Noirmont to reach Le Noirmont and was electrified in 1913. In 1927 the two companies merged to form the Chemin de fer Tavannes–Noirmont.

On 7 December 1892 the longest of the region's lines, the Chemin de fer Saignelégier-La Chaux-de-Fonds (SC) was opened linking the places in its title. The 25 km (15.5 mi) line ran from Saignelégier (Place d'Armes) to La Chaux-de-Fonds, the final kilometre being laid along the streets to the town centre.

The 1,435 mm (4 ft 8+1⁄2 in) gauge Porrentruy–Bonfol railway line and Saignelégier–Glovelier railway were opened in 1901 and 1904 respectively. Finally, Porrentruy–Bonfol was extended to Pfetterhouse in 1910. This extension was closed in 1970. The line between Saignelégier and Glovelier relaid to metre gauge in 1953.

Following the amalgamation of the companies in 1943, the rail system was restructured between 1946 and 1953. The complete system was electrified, some 40 years after the first electric trains had run.
