Between 1901 and 1910 Austro-Hungarian state railways Kaiserlich-königliche österreichische Staatsbahnen (KkStB) took delivery of 25 express locomotives classed 108. They were built by BMMF (eleven), Wiener Neustadt (eight) and StEG (six). Class 108 ran on saturated steam, featured four-cylinder compound steam engine and, for the first time in the KkStB fleet, 2-2-1 axle arrangement. Last nine engines, built from 1905 onwards, were fitted with modified boilers, with 314 flues instead of 329, and their empty weight was marginally lower. These powerful and fast for their time locomotives (140 km/h has been reported) hauled express trains from Vienna to Praha and Kraków. Eleven similar locomotives, differing in minor details, were built between 1903 and 1908 for Südbahn by Wiener Neustadt (three) and StEG (eight). They were assigned service numbers 211 through 221.
After WWI Czechoslovakian state railways ČSD took over 20 engines from KkStB. Three more (108.03, 108.06 and 108.07) went initially to Austrian state railways BBÖ, but soon were also passed over to ČSD. 108.14 was taken over by Romanian state railways CFR and retained its original service number; it was withdrawn before 1934. All former Südbahn engines remained in Austria and were given BBÖ service numbers 108.01 through 11. Last three were withdrawn in 1935.
Polish state railways received just one engine of this type, 108.15 (StEG 3068/1903). Its service in Poland was, however, destined to be short, as in 1924 it was passed over to ČSD. Class designation Pf11 was earmarked for this type, but never actually assigned. No details concerning service with PKP are available. According to EZ, Polish locomotive was in fact 108.14, although all other sources confirm that this particular example went to CFR. Czechoslovakian engines, eventually classed 275.0 (ex-PKP engine became 275.14), remained in service until late 1940s; the last one, 275.010 (formerly 108.10, WrN 4516/1903) was written off in 1950. Seven served for a few more years as stationary boilers. No locomotive of this type has survived until today.
