Yugoslav State 2-6-0 Locomotives in Yugoslavia


Class Details by Steve Llanso of Sweat House Media

Class 6000/20 (Locobase 1717)

Data from "Lokomotiva serijia 20", Skice I Podatci Lokomotiva (Zagreb: JDZ, 1955), p. 17; and A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966. A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot: David & Charles, 1966). Borsig works numbers were 11328-11374 in 1922 (6000-6047), Henchel continued with works numbers 19041-19108 in 1922 (6048-6115), Hanomag works numbers 10012-10037 in 1922 (6118-6141), AEG-Borsig 2459- 2482 (6142-6165), Krauss Munich works numbers 8036-8045 (6166-6175), and Rheinmetall works numbers 518-543 in 1922 (6176-6200).

Another Serbian design adopted and built new. As the production data show, six different builders took a part of the order--four of the established firms and two recent entrees.

Renumbered 20.001-200 in 1933.

(NB: The 1955 JDZ diagram used the 45 mm internal (fire side) diameter for its tube heating surface area calculation. Thus, the THS came to 102.4 sq m (1,102 sq ft), which combined with direct heating surface area to equal 116.6 sq m (1,255 sq ft). Locobase uses the external (water side diameter provided in the diagram to simplify comparisons with the Anglo-American preference for the external diameter.)
