Data from [] (10 July 2004). Corpet works #1667 & 1672, these tanks were used in support of public works from 1925 to 1946. The profile shows a small engine with long tanks, an outsized cab, and an even top line of two domes of equal size (steam dome ahead of sand dome) behind the very slightly flared stack.
Soon after the Chemin de Fer Baie Somme association was formed in 1971, the CFBS learned that the Plisson company, successore to P.Frot wanted to sell its steam locomotive holdings. When they viewed the engines at Troyes, it was, as the site says, like entering Ali Baba's Cave. Of the 10 locomotives, they chose 3 0-4-0Ts -- Marron, Verte, et Gris (Maroon, Green, & Grey).
Verte was the only one in service in 2004, mostly as backup to the larger CFBS locomotives.
