Nord 0-6-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 3.201 (Locobase 10468)

Data from "An Old French Locomotives," The Locomotive Magazine, Vol X (15 October 1904), p. 174.

This class was still in service almost 60 years after its introduction, which was the inspiration for the article from which the data are drawn. The first 19 were delivered by the Societe 'L'Expansion' located in Mulhouse, Derosne et Cail of Paris produced the next 25 in 1947, Gouin supplied 10 more, and 'L'Expansion' complted the class with 10 more. Although delivered with haystack fireboxes, they were soon refitted with the straightback boiler that would long be known in France as the Crampton pattern.

After 40 years on French service, 25 of the class were sold to the Nord Belge, which operated from Liege to Givet. The class's service life was nearing its end on both railways when the LM article appeared in late 1904.


Class 3.275 (Locobase 11260)

Data from Maurice Demoulin, Traite Pratique de la Machine Locomotive (Paris: Libraire Polytechnique, Baudry et Cie, 1898), pp. 110.

Even as the Nord was producing the famed Mammouth line of 6-coupled freight locomotives, it was also buying much larger engines of similar layout. See Locobase 20091 for a set of slightly lower numbers for the class.

Demoulin noted the difference and expresses a little regret that the construction of type was abandoned.


Class 3.967 (Locobase 11281)

Data Maurice Demoulin, Traite Pratique de la Machine Locomotive (Paris: Libraire Polytechnique, Baudry et Cie, 1898), p.151-152.

This batch is represented of the numerous terminal-area locomotives built for and by the Nord beginning in 1866. A Belpaire firebox replaced the Crampton (straight boiler) type in 1870. The preceding 20 engines (3.947-3.966) had square cylinders (440 mm x 440 mm) were a little less powerful and had a slightly larger grate (1.25 sq m), weight of 33 tonnes, and a shorter wheelbase of 2.28 m (7.5 ft).


Class 3453 (Locobase 11259)

Data from Maurice Demoulin, Traite Pratique de la Machine Locomotive (Paris: Libraire Polytechnique, Baudry et Cie, 1898), pp. 109.

Succeeding the 1882 version of the long-running Mammouths, this batch had taller drivers, bigger boilers, and substantially larger grates.


Class 3606 (Locobase 11258)

Data from Maurice Demoulin, Traite Pratique de la Machine Locomotive (Paris: Libraire Polytechnique, Baudry et Cie, 1898), pp. 109.

Part of the long-running Mammoth series of six-coupleds that first entered service in 1846 (Locobase 10468), this numerous class of stubby freighters had the dome over the center coupled axle. The 4-course boiler was longer and the firebox sloped, but the cylinders remained inside the frame and were slightly inclined. Their mid-range driver diameter suited them for service on both mixed-traffic trains as well as fast freights.


Class Type 20/3.275 (Locobase 20091)

Data from Locomotives Schneider et Cie (Paris : Imp. Draeger, 1920), p. 43, archived as CNAM-MUSEE TR0.5-SCH at [external link], pp. 9-10.

Locobase believes that the Mammouths shown in Locobase 11260 were a later batch than the ones that appear in Schneider's catalogue.


Class unknown (Locobase 11343)

Data from L Chatelier, E Flachat, J Petiet, and C Polonceau, Guide du Mecanicien Constructeur et Conducteur de Machines Locomotives (Paris: Chez Paul Dupont, 1851), pp. 369-370 and tables on 369-370.

This class of marchandise (goods/freight) engines used the same boiler and firebox as found in the first of the singles shown in Locobase 11341. If Locobase understands the French of the 4 noted engineers that combined to write the book from which the data comes, these engines had similar issues with poor steaming and instability. It seems that the problems showed themselves to an even greater degree and suffered from priming (bringing water into the dry pipe and thence to the cylinders) "avec une grande facilite" because of the small size of the steam space in the boiler.
