Cote du Nord 0-6-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 201 (Locobase 6221)

Data from [] (13 July 2004). See Locobase 6220 for a summary of the Lannion lacework of metric-gauge railways built in the early 20th Century in Brittany.

The first of these little tanks (smaller than the BM's shown in 6220) was originally delivered to the CF de Armorique and later transferred to the Lannion-Plestin-les-Greves line which opened in 1914. This line was never very successful and rail traffic ceased in 1935.All three locomotives were sold to the societe Saffim in 1950.


Class 210 (Locobase 6220)

Data from [] (13 July 2004).

Lannion is a small city on the northern coast (Cotes du Nord) of Brittany. In 1906 two lines opened: Lannion a Plouret (under the control of first Ouest, then Etat) and Lannion a Perros-Guirec (part of the Cotes du Nord metric-gauge network). The CdN's construction is noteworthy because it was among the first civil engineering projects to use reinforced concrete.

The author of a summary of the Lannion system comments that the Perros-Guirec line aroused so much contention and disagreement during its operational life that the CdN's chief civil engineer Harel de La Nod called it "l'HTlFne des lignes du rTseau dTpartemental" after Helen of Troy. It served a beach that grew in popularity as well as the quarries of Granit Rose de Perros-Guirec. Even though the town's citizens complained about the noise and soot from the locomotives, the line never shifted until its closing in 1948.

The Lannion-Treguier line, although leaving from the same city and operating during the same period, belonged to the CdN.

The Blanc-Misseron six-coupled locomotives are credited with two sets of works numbers. According to the account, they were Tubize/Blanc-Misseron 1420/326, 1421/327 et 1422/328. It's not clear to Locobase if that means that Tubize manufactured the machines and BM assembled them. Such engines are known as Blanc-Misseron-Tubize

At the other end of their careers, 23 & 24 were sold in 1939 while 25 was sold to the societe Saffim in 1950.


Class Corpet Lourdes (Locobase 9994)

Data from [] . See Locobase 6220 for a summary of the Lannion lacework of metric-gauge railways built in the early 20th Century in Brittany.

This doughty group of six-coupled tanks were added to the CdeN's stable as significantly more powerful younger siblings to the Corpet-Louvets shown in Locobase 5106. They served the C de N network between St Brieuc& Paimpol for 31 years until it closed in 1956. Credited with developing 365 hp, they were rated to pull 90 tonnes at speeds up to 50 km/h (31 mph) on a profile that included one 4 1/2 km run to Paimpol up a continuous 0.35%.
