French Northern Railway No. 3.078 to 3.354
French State Railway 230 A 1 to 277
The Nord had borrowed the Ten-wheeler number 1301 from the Midi at the end of 1896 in order to investigate the suitability of this type for mixed service. Due to the good results, the first 50 locomotives were ordered to haul express freight trains, heavy passenger trains and mail trains. Later their number grew to 277, which also hauled coal trains up to 1,000 tonnes and even express trains on mountainous lines. In service with coal trains they were soon superseded by locomotives with a 2-8-0 wheel arrangement, while the heaviest passenger and express trains were soon hauled by newer Ten-wheelers and Pacifics. In the SNCF they were designated 230 A and increasingly used on branch lines. Most were retired in the 1950s, the last in 1962.
