The reference for locomotives and railcars

French Northern Railway No. 401 to 436

French Northern Railway No. 2.401 to 2.436

France 1856 36 produced
Locomotive Magazine, April 1922

The French Nord received a total of 36 Engerth supporting tender locomotives for passenger transport in 1857 and 1858. They only had two driving axles with large wheels and three axles for the tender. The wheelbase between the driving axles was relatively large in order to achieve good running stability.

From 1873 onwards, eleven locomotives were rebuilt into 0-4-2 tender locomotives in the Nord workshops by separating the tender with the two axles underneath from the locomotive and installing a trailing axle instead of the first tender axle. Later, both the rebuilt and the non-rebuilt ones were used in Lille's suburban traffic. The retirements took place between 1910 and 1913.
