disposition =SM02 (model Ls40) is a Polish series of diesel shunting locomotives used by
PKP . 12 of the locomotives were introduced into PKP after1954 .cite web| url=http://157.158.1.11/~uboottd/jareks/assort/VIII.htm| title=Chester Home Page| author=Jarek D. Stwarz| date=1997-2002| accessdate=2007-08-30] It is the first diesel locomotive of Polish production.

The locomotive's designing started in
1947 on the basis of pre-war German OMZ122shunter .cite web| url=http://www.psmk.org.pl/index.php?id=zbiory/ls40| title=Polskie Stowarzyszenie Miłośników Kolei| date=2003-2007| accessdate=2007-08-30] SM02 was finally designed in the beginnings of the1950s and the production started in1952 inFablok ,Chrzanów . Before1960 those locomotives were named Lo1xx in PKP, where xx stands for numbers. Those machines did not find much of use in PKP, mainly because of poor performance features.Ls40 locomotives were nonetheless widely used in the industry. During the service S64L engines proved to be insufficient for the tasks of this locomotive, so a few last items had been equipped with more powerful S324HL motors. Meanwhile several older locomotives had their engines replaced during servicing.
Preservation
Several items of Ls40 locomotive stay in service in industry, but they are being withdrawn systematically. Ls40-5438 engine serves as an exhibit in
Skansen Parowozownia Kościerzyna museum and Ls40-4572 was bought by Polskie Stowarzyszenie Miłośników Kolei (En.: "Polish Society of Railway Enthusiasts") from Grodziskie Zakłady Farmaceutyczne "Polfa" inGrodzisk Mazowiecki onJune 30 ,1995 .Technical data
SM02 is a B locomotive, what means there are two powered
axle s under the unit. These axles are not articulated relative to other parts of the locomotive. The locomotive is proppelled by adiesel engine and the power was supplied to axles through mechanicaltransmission .
