Fablok 3DL is a Polish standard gauge diesel mechanical locomotive intended for shunting operations built by Fablok in Chrzanów between 1936 and 1938. The first example was designated 627/1936, and the second example was designated 655/1936, the later examples designation is unknown.

After the 2DL prototype was built, the 3DL locomotive was made in 1936 which was slightly better than the 2DL prototype, but had less power and speed, it was based on a locomotive documentation purchased by Deutz in 1932.[1] 3DL had a 4-cylinder Deutz A4M220 diesel engine imported from Germany, 4 geared mechanical gearbox licensed by Deutz, pneumatic brakes and headlights powered by electricity.[2] 3DL could reach the maximum engine power rated 100 horsepower, it also had a truss drive which could be installed in an additional transmission for 2 maximum speed ranges (21 km/h/48 km/h).[2] 3DL locomotives were the successful example by Fablok.

3DL had total length of 6,920 mm, cab length of 2260 mm, coupling rods length of 2,500 mm, height to the buffer of 1,045 mm, height to the locomotive nose hood of 2,400 mm and a total width of 3,000 mm. The largest weight of the wagon train driven on a straight and horizontal tracks was 1030 tons.[2]

3DL locomotives were intended for shunting duties at minor sidings on the industrial areas. The first locomotive (627/1936) was bought by a chemical plant along with the second example (655/1936), 7 more locomotives were built until 1938 in which 4 went to the chemical plant and the 3 sold to the armament industry plants.[1]
