2-8-2 Steam Locomotives in Yugoslavia

Yugoslav State


Class Details by Steve Llanso of Sweat House Media

Class 06 (Locobase 1715)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and [], the Slovenian Railway Museum website, (Many thanks to Aljaz Skarlovnik for his 19 July 2019 email supplying more information about these locomotives.)

Part of a three-type procurement described in Locobases 1714-1716, which show Class 05 4-6-2, Class 06 2-8-2, and Class 30 2-10-0, respectively. Locobase notes that all three designs rolled on six axles with adhesion and axle loading requirements doubtless dictating the variations. Works numbers were 12190-12219 in 1930.

Based in Ljubljana and originally worked passenger service before being relegated to freight duties.This variant had a big firebox for burning poor-quality coal and relatively low drivers for the mountainous profile she ran over.

Renumbered 06.001-030 in 1933.


Class 85 (Locobase 20967)

Data from A[nthony] E[dward] Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp. 132, 134. See also Dave Sallery, The 76 cm railways of Yugoslavia, archived at [][], last accessed 18 December 2021. MAVAG delivered the first 35 with Slavonski Brod later adding another ten.

Durrant noted that these locomotives replaced older 0-8-2s and were faster, "but slower than the sprightly old 2-6-2s. Fitted with superheaters and piston valves and using a larger boiler, they became "the standard heavy-duty mixed-traffic engines."
