CMN or Chemin de Fer des Montagnes Neuchâtelois is a 20 km piece of narrow gauge railroad from the town of Neuchâtel by the Lake Neuchâtel (and the main train line) up the steep hills to the town of La Chaux de Fonds close to the French border. La Chaux de Fonds is actually a fairly large town, Swiss in style but almost completely French in terms of inhabitants, language and connections. These small CMN one coach trains and the road along the extremely steep hillside are the only real connections to Switzerland, but connections to France are good and lively.

CMN has 3 old (from 1950) and 3 modern one coach electric motor units. This one, no. 6, is the first of the newer series, built in 1991. It is 20,70 m long, weighs 35,5 tons, has a maximum speed of 80 km/h and operates on 1 meter gauge tracks with 1500 V DC. The railroad has been in operation since 1889.
