Tank switcher with a small coal bunker and sloping tanks. Wikipedia stated that these were designed to replace the class 30 0-6-0s. Only 20 left the builders before the First World War intervened and the last two were commandeered by the advancing Germans.
Six years later, the Est picked up the thread

A long-boilered freight engine with the tall dome positioned over the first driving axle, just behind the even taller stack. Roland Arzul's website of French locomotives -- [], last accessed 22 June 2006 -- notes that this design was the inspiration for the P O's 1114-1140 class. They ran on the Clemont-Ferrand line in mixed-traffic duties.
Although given a class designation by the SNCF, the class never actually operated for the national line. Some were sold to the Algerian Railway, where they ran until 1940.
