See also A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot: David & Charles, 1966). Krauss Linz works numbers were 5972, 6029-6035 in 1909, 6442-6445 in 1911, 6583-6584 in 1912, 6725-6730 in 1913, 7141-7144 in 1916, 7289-7300 in 1917, 7500-7503 in 1919. Hungary's Budapest works numbers were 2674-2676 in 1911, 3030-3031 in 1912, 3577-3576 in 1914, 3966-3969 in 1916
A long-lived class long in production, this useful mountain engine was designed for the Bosnian railways at the turn of the 20th Century. It first entered production as Class IVa at the Krauss works in Linz, Austria (then Austria-Hungary). Further batches from Krauss were supplemented by production at MAVAG's plant in Budapest over the next decade.
After World War I, Jung (in Jungenthal) produced dozens more two-cylinder simple-expansion variants; see Locobase 4804.
Switzerland's Club 760 bought the out-of-service 83.076 in 1987 and leased it to the Zillertalbahn railway. The Zbahn contracted in 1993 with Dampflok Meiningen (then Reichsbahnausbesserungswerk Meiningen) to restore the engine, which went into service as #4. (See [] for a detailed elevation drawing and data.)
Information from Dieter Zoubek, webplanet.lion.cc/erde/310150/details/jz83.html; "Lokomotiva serijia 83 (Blizna)", Skice I Podatci Lokomotiva (Zagreb: JDZ, 1955), p.64; and A E Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp. 132, 134. Jung (in Jungenthal) produced 24 in 1923 (works numbers were 3527-3550 in 1923) and Budapest added the largest single batch of 44 in 1929 (Works numbers 4963-5007). Years later, after World War II had devastated most European railways, the Yugoslavian works Duro Dakovic and Budapest produced 30 more Class 83s and MAVAG 6 engines in 1948-1949.
A long-lived class long in production, this useful mountain engine was designed for the Bosnian railways at the turn of the 20th Century. Produced in large numbers as saturated-steam compounds before World War I (Locobase 4803), the design reappeared in the 20s as a two-cylinder simple-expansion engine with lower pressure but a significant amount of superheating surface.
As late as 1966, Jugoslavian railways still operated 169 Class 83s, most from Sarajevo. The last Bosnian 83 dropped fires in May 1979. Some of these went to Banovici to work the coal mines and were still in use in 1998.
