Warszawska Spółka Akcyjna Budowy Parowozów (Warsaw Joint-Stock Company for Steam Locomotive Manufacturing) was founded in 1920 as one of three Polish locomotive manufacturers. As a result of serious financial problems, it was sold to Zakłady Ostrowieckie (Ostrowiec Works) in December 1934 and became their division. Although re-named Wytwórnia Parowozów Zakładów Ostrowieckich (WPZO Steam Locomotive Manufacturing Plant of Ostrowiec Works), it no longer produced standard-gauge steam locomotives, concentrating on internal combustion engines, power rollers and boilers. In 1936 the company built four small two-axle switchers, powered by FIAT 118A petrol engines rated at 35 hp and hence referred to as FIAT 35. The choice of prime mover seems somehow strange, as WZPO produced successful diesel engines. Factory numbers of these locomotives are not known, as well as their technical data, including dimensions and weights.

FIAT 35 was a simple design, with four-speed Mylius gearbox and chain transmission to both axles. It could haul a 100-tonne draft at 12 km/h. One example was sold to Schicht-Lever adipose industry plant in Warsaw; it survived the war and remained in use until 1952, but has not been preserved. Three remaining locomotives of this type were purchased by military authorities and reportedly used at the ammunition dumps in Palmiry near Warsaw. Their ultimate fate is unknown.
