Even though this quartet of Singles entered service four years later than the P-O's Type 4 (Locobase ), their boilers were heated by a haystack boiler that featured a semicircular cap. Outside frames used gentler curves to clear the taller drivers on both sides.
Reflecting an uncertainty about how locomotives should be guided around curves, small wheels on stalks that extended down to rail level to put small, nearly horizontal guide wheels ahead and behind each of the four unpowered wheels.
Locobase suspects that the Paris-Sceaux soon found the extra help unnecessary.
