Nord 0-8-4 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 361 (Locobase 20895)

Data from Albert Jacquet, "'Engerth'" Locomotives on French and Belgian Railways", Locomotive Magazine, Volume XXVIII [28] (15 March 1922), pp. 74-77.Works numbers were 1-10.

Jacquet reported that these Engerth developed the same power as the Nord class shown in Locobase , but weighed a bit more. Like the 371s, this class pulled trains in the Nord and Pas de Calais regions for decades with little modification. They were regarded as very successful goods locomotives.

NB: Jacquet's data for tube heating surface used the internal tube diameter, which yielded 184.6 sq m) (1,987 sq ft) and evaporative heatng surface of 208.2 sq m (2,114 sq ft). Locobase uses the external diameter given in the Jury report to simplify comparison with Anglo-American designs.


Class Type 28 (Locobase 20427)

Data from Schneider Catalogue, last accessed 27 August 2018 at [link], pp. 10-11. Albert Jacquet, "'Engerth'" Locomotives on French and Belgian Railways", Locomotive Magazine, Volume XXVIII [28] (15 March 1922), pp. 74-77.Works numbers were 212-241 in 1855-1856. (Jacquet wrote 212-221 and 247-266.)

Engerth goods tanks about which Jacquet found only praise. In more than five decades of work in the Nord and Pas de Calais districts, the Nord engineers "never deemed it necessary to follow the example of the Eastern Co [which converted their Engerths to tender-separate 0-8-0s] maintaining the engines in service without any modification until the end of their career.

For this effort and for the general quality of the design and construction, the Jury awarded "la grande medaille d'honneur".

NB: Jacquet's data for tube heating surface used the internal tube diameter of 49 mm (1.93"), which yielded 186.65 sq m) (2,009 sq ft) and evaporative heatng surface of 196.4 sq m (2,114 sq ft). Locobase uses the external diameter given in the Jury report to simplify comparison with Anglo-American designs.
