Ultra-low drivered elongations of the three-axle Bourbonnais freight locomotive, these engines were the first of the four-axle tender-engines that became so numerous in France and other European countries. The connecting and main rods had round cross sections, external valve gear based on the Crampton design, and solid drivers. The rear axle enjoyed a great deal of lateral play to allow the engine to negotiate tight curves.
The prototype proved successful -- a level run of 1,050 tons achieved 14 mph and an uphill pull (2.5% at 12 mph) managed 112 tons -- and was followed by 23 slightly more powerful engines.
