These little maintenance-of-way switchers had a vertical boiler with two lengths of tubes. All of them had exterior diameters of 55 mm (2.17 inches), but the 30 long ones measured 850 mm long (33.5 inches) and the 68 short tubes were 500 mm long (19.7 inches).
The engines were renumbered 7 038-7 040 in 1911 and 7 001-7 003 in 1914-1918. All were still in use when the PLM went into the SNCF in 1938. Later they were rebuilt as crane tanks with a capstan winch in front using a 3-cylinder, steam-powered Brotherhood engine.

Similar in arrangement to the maintenance-of-way tank described in Locobase 13368, this pair came from Pittsburgh, PA after World War One. Both were later converted to gas-powered locomotives using a 7-hp Dake motor.
