The NMBS/SNCB Type 36 was a class of 2-10-0 Decapod steam locomotives built from 1909 to 1914 for heavy freight service in Belgium operated by the National Railway Company of Belgium.

[1] The class was designed by engineer Jean-Baptiste Flamme and built by NMBS/SNCB themselves, in their central railway workshops in Mechelen, Belgium.

It was decided to sell 80 of them to the Russians, these would serve on the standard gauge lines of Galicia and in eastern Poland.

21 examples remained in France because of the Russian Revolution of 1917 and the armistice signed with the Germans.

It is also thought that some locomotives were in Ukraine during Operation Faustschlag and subsequently brought back by the Germans.
