Chemin de fer des Côtes-du-Nord

The lines were a voie ferrée d'intérêt local system with a total extent of 457 kilometres (284 mi).

The system was constructed in two stages, the initial lines built between 1905 and 1907, and the extensions during and after the First World War which were opened between 1916 and 1926.

The first closures were in 1937, but the Second World War gave the CdN a stay of execution, and parts of the system remained open until 1956.

The engineer was Louis Auguste Marie Harel de la Noë, who built many of the bridges and viaducts in concrete.

Although some lines were reopened during World War II, by 1950 the only section open was St. Brieuc – Paimpol, which closed on 31 December 1956.

The line was very close to the coast in places, and heavily engineered, with thirteen bridges in 3 kilometres (1.9 mi).

There were two major bridges on the line, the Viaduc de Lézardrieux near Trieux (160 metres or 525 feet long and 30 metres or 98 feet 5 inches high) and the Viaduc sur le Jaudy at Tréguier.

Reconstruction started in September 1946 but the central arch collapsed and the work was abandoned.

The failure to rebuild the bridge accelerated the closure of the line west of Paimpol.

The only major bridge was the Pont sur le Léguer between Lannion-Ouest and Lannion-Ville.

The line was closed for four days in 1918 after damage caused by high tides between St. Efflam and St.

The 22.7-kilometre (14.1 mi) line between Petit Camp and Perros-Guirec opened on 11 August 1906 and closed on 15 April 1949.

The major bridges on this section of line were the Pont sur le Jaudy at La Roche Derrien, the viaduc de Loquélo at Minihy-Tréguier and the Pont du Chef du Bois at Pommerit-Jaudy.

[2] The 39.6 kilometres (24.6 mi) line between Guingamp and St. Nicolas opened on 12 January 1924 and closed on 1 August 1938.

[2] The 25.6 kilometres (15.9 mi) line between St. Brieuc and Moncontour opened on 1 May 1905 and closed to passengers on 1 April 1937.

At Langueux, a branch was built to serve a brick and tile works, which supplied materials for the construction of the stations of the CdN.

[2] The 15.7 kilometres (9.8 mi) line between Moncontour and Collinée opened on 1 July 1907 and closed on 24 April 1939.

It was on this line that the CdN reached its highest point of 300 metres (984 ft 3 in) above sea level.

The 11.4 kilometres (7.1 mi) line between St. Alban and Lamballe opened on 11 July 1922 and closed on 31 December 1948.

Lamballe station was also served by the Rennes – Brest line of the CF de l'Ouest.

This isolated section of the CdN was linked to the rest of the network in 1926 with the opening of the Yffinac – Matignon and St. Brieuc – St.

The section between St. Briac and Lancieux opened in 1932 and the entire line closed on 15 February 1939.

[2] During World War Two, the CdN was requisitioned by the Germans for the construction of the Atlantic Wall.

One of the most impressive was the destruction by the French Forces of the Interior of the viaduct between Jaudy and Tréguier on 15 August 1944, splitting the network in two.

Based on the site of Boutdeville at Langueux (near Saint-Brieuc), they aim to recreate about 3 kilometres (1.9 mi) of line as a tourist attraction.
