The Réseau Breton (, RB) is a , standard gauge, and former , metre gauge, railway in Finistère, France, with a few kilometres of line in Côtes d'Armor, Ille-et-Vilaine and Morbihan. The hub of the system was Carhaix. The metre gauge lines were built with the capacity to be easily converted to standard gauge if necessary.
History
Background Brittany in the mid nineteenth century was a largely agricultural area. the quarrying of slate and granite also took place. Forests in inland areas had previously supplied timber for construction of buildings and shipbuilding at the larger coastal ports, but this industry had largely declined as the source material was exhausted and the land turned over to agriculture. Apart from roads, the first transportation system constructed in Brittany was the Canal de Nantes à Brest, started in 1811 and completed in 1842. Although the canal could carry high volumes of freight, it was slow, relying on horse-drawn barges.
Railways The first standard gauge railways in Brittany were the Chemin de fer de Paris à Orléans (CF PO) line from Paris to Quimper, which was completed in 1863 and the Chemins de fer de l'Ouest (CF de l'Ouest) line from Paris to Brest, which was completed in 1865. The CF PO built a line from Quimper to Châteaulin and Landerneau, where it connected with the CF PO. This line was completed in 1867. The CF PO built a line from Auray to Pontivy, which was completed in 1864. In 1872, the CF de l'Ouest built a line from Saint Brieuc to Pontivy, where it connected with the CF PO line. These lines left central Brittany an area devoid of railways, and served only by the Canal de Nantes à Brest.
In 1880, the concession to build an Intérêt Générale system in Brittany was given to the CF de l'Ouest. It was agreed that the lines would be built to metre gauge, but provision would be made for conversion to standard gauge should the need arise. Morlaix would be the administrative headquarters, but Carhaix would be the main station, with engineering workshops, locomotive depôt and carriage workshops. The first line opened in 1891 and further extensions until 1925 gave the network a total length of of metre gauge line. The lines closed to passengers in 1939, but with the replacement buses being requisitioned at the outbreak of the Second World War the passenger service was resumed, with a couple of trips daily on each line. The RB saw an increase in freight traffic, being used to transport materials for the Atlantic Wall. After the war, passenger services were gradually withdrawn, and all metre gauge lines closed on 9 April 1967 with the section between Carhaix - Paimpol having been converted to dual gauge in 1924 and converted to standard gauge in 1953, and Carhaix - Guingamp, closed in February 1967 for conversion to standard gauge later in 1967, remaining open.
Lines
Metre gauge The metre gauge lines of the RB were:-
Carhaix – Morlaix
The line from Carhaix to Morlaix opened on 28 September 1891.. Carhaix station was the headquarters of the RB. All five lines that made up the main RB system originated from Carhaix. The station is located to the east of the town. In common with many of the station on the RB, Carhaix was architecturally similar to may CF de l'Ouest stations.
The lines of the RB were mainly built with Moroccan labour. Many of the stations were not in the settlements they purported to serve. Often a double-barrelled name indicated that the station lay between two places. Leaving Carhaix, the railway shared the trackbed with the line to Guingamp until it curved to the left and crossed the D787 road. The first station was Plounézéval Halte, (). The halt actually stood in Le Frostel, some from Plounézéval. Pouallaouen () was the next station. The Ulne was crossed on a high stone arch bridge before Huelgoat-Locmaria () was reached. This station stood in Locmaria-Berrien and was some () from Huelgoat. The d'Argent was crossed by a steel bridge before Kervallon Halte () was reached. Here, the line passed to the east of the Forêt Domaniale de St-Ambrose. Scrignac-Berrien station () was about () from Scrignac and Berrien. Kermarzin () and Le Cloître-Lannéanou () stations were followed by the summit of the line (over ) before Ploungonven-Plourin () was reached.
At Morlaix the line was shared with the CF de l'Ouest's standard gauge dual gauge line between Paris and Brest. A dual gauge section of track was laid on the up line on the viaduct across the harbour. This was built by the CF de l'Ouest as part of their Paris - Brest line. The viaduct crossed the Chemins de fer armoricains (CFA) Morlaix - Plestin-les-Grèves line. A platform at Morlaix was shared with the standard gauge. A branch was opened on 12 February 1906 to serve the port at Morlaix. Freight traffic beyond Plougonver ceased from 25 September 1962. The line between Carhaix and Morlaix closed completely on 9 April 1967.
Carhaix – Paimpol
The line from Carhaix to Guingamp opened on 24 September 1893, and was extended a further to Paimpol on 14 August 1894. The line between Guingamp and Paimpol was converted to dual gauge in the early 1920s with the addition of a third rail for standard gauge traffic. The standard gauge line opened to traffic on 24 May 1924. When the extra rail was added, gangs started from each end of the line, laying the extra rail to the left as they were facing the line. They met near Lancerf, where an arrangement had to be arranged to allow the metre gauge track to switch sides. This was known as the Sauterelle (), the term being a corruption of saut rail (). The sauterelle had to be approached slowly. In 1953, the metre gauge rail was removed between Guingamp and Paimpol, the line operating as standard gauge since then. The metre gauge line between Carhaix and Guingamp closed on 14 February 1967, re-opening as a standard gauge line on 3 July 1967.
The first station is Carnoët-Locarn (), the station being nowhere near either village. Le Plenity Halte () is next. Although plans were made to upgrade this to station status and provide full facilities, these were not carried out. Callac () is next, followed by Le Mais Halte (). Plougonver () and Pont Melvez () stations are followed by Coat-Guégen Halte (). Moustéru station () is the last before Guingamp (). At Guingamp there were loco sheds and facilities to service metre and standard gauge rolling stock. There is a connection with the standard gauge Paris - Brest line.
Guingamp station had a connection with the Chemin de fer des Côtes-du-Nord (CdN) Guingamp - Plouha and Guingamp - St. Nicolas du Pélem lines. Gourland station () is next, followed by Trégonneau-Squiffec () then Brélidy-Plouëc (), which is nearer to La Belle Eglise than Brélidy or Plouëc de Trieux. Plouëc had a connection with the CdN Plouëc - Tréguier line. Leaving Brélidy-Plouec, the line heads for the Trieux. After leaving Pontrieux Halte (), the Trieux is crossed by a six-arch viaduct before Pontrieux () is reached. A branch here served the port. The Leff is crossed by a steel bridge on the approach to Frynadour (). Lancherf () and Plounez () are next, before the terminus at Paimpol Station (). A branch at Paimpol served the port. Next to the RB station was a CdN station which served the Paimpol - Tréguier and Paimpol - Plouha lines. The CdN line between Paimpol and Tréguier crossed the branch to the port on a flat crossing.
Carhaix – Rosporden
The line from Carhaix to Rosporden opened on 2 August 1896. Leaving Carhaix, the N164 Angers - Brest road was crossed by a skew bridge. The railway crossed the Canal de Nantes à Brest before Port de Carhaix station () was reached. On leaving Port de Carhaix, the D769 road was crossed. Motreff () was the next station. It was () from the town. Gourin station () was also the terminus of the Chemins de fer du Morbihan (CM) line to Meslan, although there was no direct link here between the two networks. Kerbiquet () was the next station, then Guiscriff (), Scaër () and Coatloc'h () stations were followed by Kerneval Halte () before Rosporden station () was reached. Rosporden station had a connection with the standard gauge Chemin de fer de Paris à Orléans (CF PO) Savernay - Landerneau line and there was an end-on junction with the CFA Rosporden - Landivisiau line.
Carhaix – La Brohinière
The almost long line from Carhaix to La Brohinière opened in sections between 1898 and 1904. Carhaix - Rostrenen opened on 15 May 1898. Rostrenen - St. Lubin-le-Vaublanc opened on 17 August 1904. St. Lubin-le-Vaublanc - Loudéac opened on 1 October 1904. Loudéac - La Brohinière opened on 12 August 1907. The line between Loudéac and La Brohinière closed to passengers in October 1953. The line closed entirely on 9 April 1967.
Leaving Carhaix, the line initially ran parallel to the Morlaix and Guingamp lines before climbing and heading east when the other two line curved away to the left. The line crossed the D20 road then followed the D49 road. Trébrivan - Le Moustoir Halte () was the first stop, followed by Maël Carhaix (). On leaving Maël Carhaix, the line followed the D23 road. La Croix Madelaine Halte () was followed by Rostrenen (). Rostrenen was the terminus of the CdN line from Saint-Nicolas-du-Pélem, the Cdn station was adjacent to the RB station. Plouguernével () was the next station. The Blavet was crossed by a steel girder bridge before Gouarec station () was reached. A branch was opened on 1 June 1912 serving the port at Gouarec.
Bon Repos Halte () and Saint Gelven Halte () were followed by Caurel (). Here, the railway ran high above the Lac de Guerlédan. At Mûr de Bretagne (), a branch served a quarry. After closure, the section of trackbed between Caurel and Mûr de Bretagne was used for the short-lived long Réseau Guerlédan, which opened on 2 July 1978. The next stations were St Guen () and St Caradec (). Loudéac station () was shared with the CF de l'Ouest, lying on that company's St Brieuc - Pontivy line. The CdN line from Plémy also terminated at Loudéac. Full facilities were provided here, the turntable being a dual gauge one, shared with the CF de l'Ouest.
Leaving Loudéac, the line crossed the standard gauge CF de l'Ouest line on the level. Ganland Halte () was followed by La Chèze St Barnabé (), Plémet La Prénassaye () and St Lubin le Vaublanc () stations. Le Carguier Halte () was followed by Laurenan (), Merdrignac () and Trémorel () stations. After Loscouet Halte (), the CF de l'Ouest's La Brohinière - Ploërmel line was crossed on the level before St Meén station () was reached. The RB then ran parallel to the CF de l'Ouest. Le Crouais Halte () was followed by the terminus at La Brohinière (), where there was a connection with the CF de l'Ouest's Paris - Brest line.
Carhaix – Camaret The line from Carhaix to Camaret opened in stages between 1893 and 1925, bringing the total extent of the RB to . Carhaix - Pleyben opened on 30 August 1904. Pleyben - Châteaulin Ville opened on 4 August 1906. Châteaulin Ville - Châteaulin Gare opened on 11 August 1907. Châteaulin Gare - Crozon-Morgat opened on 13 August 1923. Crozon-Morgat - Camaret and Le Fret opened on 14 June 1925. Châteaulin Gare station had a connection with the CF PO Savernay - Landerneau line. The line between Perros St. Fiacre and Le Fret closed to passengers in May 1946.
