A nice array of SNCF tank engines on shed dominated by the 141TB class of 2-8-2T but which dépôt is this?
This, resulting from astute deductions by a French viewer is an answer: "En effet, on n'a pas de certitude, mais je crois que tu tiens la solution : Vaires (ou région parisienne) en 46 ou 47.
Vaires-sur-Marne étant près de Paris, la présence de machines de la Villette ou de Noisy en attente pour ramener un train de banlieue est plausible. Par contre, la machine d'Epinal ou de Nancy n'a pas l'autonomie nécessaire pour venir à Paris (et les autres ne sont pas capables non plus de partir si loin dans l'Est)."
I have a slightly different opinion although I have no doubt that the location, Vaires, is correct. I think that this image depicts an accumulation of withdrawn locomotives and was taken shortly after the 141 TB's were displaced from the Bastille services by electrification which suggests that this is 1966 rather than 1946. It does mean that one of the depicted 141 TB's doesn't actually belong to the Vaires depot but that was commonplace during the mass withdrawals in the UK during the 1960's when entire classes would be congregated in one depot - regardless of their originating depots - before being moved to the scrap merchant.
