They passed to the Chemins de fer du Nord in 1934 who renumbered them 3.701 to 3.715. In 1938 they passed to the SNCF who renumbered them 230.TA.1 to 230.TA.6. HistoryThe chief mechanical engineer of the Nord Gaston du Bousquet designed a series of fifteen push-pulltank locomotives for the Ceinture that were capable of rapid acceleration due to the frequent stops. The first batch of locomotives were built by the Nord's Hellemmes workshops; they were followed by a second batch built by the Nord's La Chapelle workshops. They entered service on the 1 April 1903.[1] In 1934 at the dissolution of the Syndicat, the Nord renumbered them 3.701 to 3.715. In 1936, the Nord rebuilt 3.702 (ex Ceinture 52) with a larger rear bunker and a trailing axle,[2] making it a 4-6-2T. The Nord did not renumber it, as their numbering system only encoded the number of driving axles. The SNCF initially failed to notice that the locomotive was different from its sisters, and initially renumbered it 230.TA.1; when the error was spotted it was renumbered 231.TA.1.{{sfn|Davies|1997|p=157}} Also in 1936 four locomotives were scrapped, and two were sold the {{ill|Compagnie générale de voies ferrées d'intérêt local|fr}} (GCL). Three more were sold the following year leaving just six to enter service with the SNCF in 1938; however two of these were sold in April 1939 without receiving their SNCF number.{{sfn|Davies|1997|p=157}} The remaining four were scrapped between 1939 and 1947. The CGL used their locomotives on the {{ill|Chemin de fer d'Achiet à Bapaume et Marcoing|fr|lt=Chemin de fer d'Achiet à Bapaume}} and {{ill|Chemin de fer de Vélu-Bertincourt à Saint-Quentin|fr}} lines. The last CGL locomotive to be scrapped was the former Nord 3.713 (née Ceinture 63) which was scrapped at Bapaume in 1960.{{sfn|Davies|1997|p=157}} DescriptionThe boiler was based on that used on the "Revolvers" (Nord 2.231 to 2.305 series) and had a Belpaire firebox. The dome was mounted on the first ring, and a sandbox was mounted on the second. {{sfn|Davies|1997|p=157}} The locomotives were four-cylinder tandem compounds: the rear high pressure cylinders were mounted on the same piston rod as the front low pressure ones.
