Imperial-Royal State Railways class 29

The class 29 was the superheated variant of the class 229 two-cylinder compound 2-6-2T. The diameter of the high-pressure cylinder had been increased by 30 mm to account for the greater power. The water tanks had been made smaller, what was roughly offset by the lower consumption due to the superheater. They still had drivers of 1,614 mm and were approved for a speed of 80 km/h. 36 were built in 1912, 33 of these by BMMF and three in Floridsdorf. Despite their higher power and lower consumption, the kkStB kept ordering the simpler 229 until 1918.

After World War I, one came to the SHS state as 116-017 and nine became PKP OKl11. The other 26 stayed in Austria and were used by the BBÖ under the same class number 29. When Austria was annexed by the Germans in 1938, they became Reichsbahn class 75⁸. After the Second World War, two were directly withdrawn and 34 remained. Of these, 16 stayed in Austria and became ÖBB class 175. Now five others were in Poland, seven in Yugoslavia and six in Czechoslovakia. The PKP had already withdrawn all in 1953, but the ÖBB kept the last one until 1962. Today the original 29.22 and later 175.817 can be found in the Museum at Strasshof in a badly deteriorated state.
