Data from G Humbert, Traite des Chemins de Fer d'Interet Local (Paris: Ch Beranger, 1893) , p. 264-265.
Humbert describes these tanks as of moderate ("moyenne") power (between forte and faible) and gives details for two different RS I-et-L classes - l'Yonne and Seine-et-Marne; the other is shown in Locobase 9432. Compared to Charente engines, this class had shorter tubes and a smaller firebox. Both classes had the drive on the third coupled axle.

Humbert describes these tanks as of moderate ("moyenne") power (between forte and faible) and gives details for two different CFD railways; the other is shown in Locobase 9431. Compared to other Reseau Sud d'Indre-et-Loire engines, this class had slightly longer tubes and a deeper firebox. Both classes had the drive on the third coupled axle.
