Jura industriel


The Compagnie du Jura industriel is a former Swiss railway company. It existed from 1857 to 1875 and operated the Neuchâtel–Le Locle-Col-des-Roches railway.
The goal of the Jura industriel was to connect the watch industry of the Neuchâtel Jura by rail to Neuchâtel.

History

In 1853, it became apparent that the canton of Neuchatel wanted to connect the French railway network to the network of the Franco-Swiss Company. The Compagnie du Jura industriel received a concession from the canton in 1854 to connect Le Locle and La Chaux-de-Fonds to the Swiss network in Neuchâtel.
Niklaus Riggenbach was appointed as a consultant for the construction of the approximately 40-kilometre-long line. The line from Neuchâtel follows a steady climb of 2.7% to the zig zag in Chambrelien and then along the slopes of the Val de Ruz and through two tunnels up to La Chaux-de-Fonds. From there, the line climbs 2.5% to Le Locle.
Railway construction began in 1854 and the first stage, the 7 kilometre-long line from La-Chaux-de-Fonds to Le Locle, was opened on 2 July 1857.
On 27 November 1859, the line was extended from La Chaux-de-Fonds to Convers at the north portal of the 3259 metre-long Les Loges Tunnel. Four days later, on 1 December, the line was opened from Neuchâtel to Les Hauts-Geneveys at the south portal of the tunnel. From the outskirts of Neuchâtel, the JI was able to use an already-built line intended for the line to Pontarlier. Due to changes in the plans of the Franco-Swiss Company during construction, this section was never used as originally intended. The opening of the whole route from Neuchâtel to Le Locle took place on 15 July 1860.
The station buildings were all built of wood, except at La Chaux-de-Fonds, which was built out of stone as JI's operations centre.
The company fell into financial difficulties shortly after the completion of the line, not least due to large interest charges, and went bankrupt on 3 January 1861. The canton continued to operate the railway and in January 1865, a new Jura industriel company was established to succeed it. Ten years later, the Neuchâtel voters rejected the repurchase of the railway and the company decided on 1 May 1875 to sell itself to the Chemins de fer du Jura bernois, which was founded on 30 April 1874. The JB was later renamed the Jura-Bern-Luzern.
The planned extensions of the line from Le Locle to the Col des Roches and on to Besançon was opened in 1884. The Chemin de fer Régional des Brenets commenced operations on its narrow-gauge line between Le Locle and Les Brenets in 1890.
The JBL apparently did not live up to local expectations and a referendum on 29 June 1884 led to the canton buying back the line. Operations were transferred to the Jura neuchâtelois company on 1 January 1886.

Rolling stock

The Jura industriel rolling stock consisted exclusively of Engerth locomotives, which had proven their worth elsewhere on steep grades. Since the first three locomotives by no means met the requirements due to their weak traction, they were later used on other lines and for shunting from 1877 and scrapped early.

Due to financial difficulties the JI could not fully pay for locomotives B numbers 4 to 7, which it had ordered, so the SCB retained locomotive number 6 and used it itself.
