Nord 2.231 à 2.305 were suburban 4-4-4T locomotives of the Chemins de Fer du Nord.[1] They were nicknamed "Revolver" due to the appearance of the high-pitched small diameter boilers next to the low water tanks and cabs,
At nationalisation on 1 January 1938, they all passed to the Société nationale des chemins de fer français (SNCF), who renumbered them 2-222.TA.1 to 2-222.TA.75.
The locomotives were built in three batches at the Nord's two workshops at La Chapelle, Paris and Hellemmes, Lille.
