The SM02 was the first diesel locomotive built in Poland. From 1952, 581 of these small shunting locomotives were manufactured in the Feliks Dzierzynski locomotive factory (later Fablok) in Chrzanów and sold by the manufacturer as the Ls40 type. The Polish State Railways only procured twelve examples, which were classified there as the SM02 series. With a maximum speed of 11 km/h, a range of 60 km and an output of 44 hp, they could not be used in larger train stations, which is why they were mainly used in industrial companies. The power was transmitted mechanically to one of the axles, which drove the second axle by means of coupling rods. Over time, many of the locomotives got a new type S324HL engine, which delivered either 60 or 75 hp. Many engines were still in use up until the 1990s, but most of them became superfluous due to the abandonment or dismantling of many industrial tracks. A few are still in use today, others are preserved either as a memorial or in the museum.
