After WWI Polish state railways PKP received considerable number of Austrian light freight locomotives with the 0-3-0 axle arrangements, many of them previously operated by various private railways. These mostly elderly and weak engines were suitable only for secondary lines and quickly disappeared from the company’s rosters. Initially they retained their original service numbers. In accordance with the new system, which came into use in 1926, they were assigned class designations in the range from Th11 to Th24. In several cases assignment of individual designations to locomotive types is not known, as they were represented by few examples and soon withdrawn due to obsolescence. One of the most numerous was the Kaiserlich-königliche österreichische Staatsbahnen (KkStB) class 54, which became PKP class Th17.

In fact class 54 comprised locomotives initially built for as many as five operators. Its design was based on that of the Kaiser Ferdinands-Nordbahn class Vd (later KkStB class 51). The first customer was Mährisch-Schlesische Centralbahn (MSCB), which commenced operation in 1872. This company received fourteen examples, built by WLF (Floridsdorf) in 1872 and 1873 and numbered 1 through 14. In 1895 MSCB was nationalized and these engines became KkStB 5450 through 5463, later 54.50 through 54.63. In 1873 Kronprinz Rudolfs-Bahn (KRB) received six locomotives, also from WLF, plus one more in 1877. They were numbered 130 through 142 (only even numbers) and after nationalization in 1884 became KkStB 5104 through 5110, later 5441 through 5447 and finally 54.41 through 54.47. Next two numbers were assigned to engines operated by K.k. Staatsbahn Tarvis-Pontafe, built by WLF in 1879 and initially numbered 200 and 202. In 1884 Galizische Transversalbahn took delivery of 36 locomotives, numbered 1111 through 1144, 1147 and 1148, built by WLF (20), Wiener Neustadt (six) and Borsig (ten). Later they were re-numbered 5401 through 5436, then 54.01 through 54.36. Finally in 1885 Wiener Neustadt built two more engines for this operator (1151 and 1152, then 5439 and 5440, finally 54.39 and 54.40) and two for Mährische Grenzbahn (MGB), nationalized in 1895 (332 and 333, then 5437 and 5438, finally 54.37 and 54.38). This gives the total of 63 examples. Locomotives built for various operators differed in certain details; basically three variants can be distinguished. All were given individual names. They were coupled with a variety of two- or three-axle tenders.

PKP took over most of these already obsolete locomotives: all but one from Galizische Transversalbahn (which ran within new Polish borders), all but two from MSBC, four from KRB, both from MGB and one from K.k. Staatsbahn Tarvis-Pontafe, which makes 55 examples. Czechoslovakian railways ČSD received five, classed 313.1; of these, 313.102 (WLF 126/1873), former KRB 138 ’Steg’, then 54.45, survived until 1948 as the last engine of this type in use. BBÖ kept only 54.51, former MSCB 2 (WLF 59/1872), withdrawn in 1925. Single examples went to Romanian CFR (withdrawn before 1934) and Italian FS (217.001, withdrawn in 1923). According to KT, all Polish engines were written off before 1924. However, official list of locomotive types, issued by the Ministry of Transport in 1927, gives 22 examples still in service. They were withdrawn before 1931 and assignment of PKP service numbers to individual examples is unknown. No locomotive of this type has been preserved.

After WWII designation Th17-1 was assigned to ex-DRG 53 7405. This engine was originally built for Buschtěhrader Eisenbahn by Wiener Neustadt (s/n 3393/1890) and later became ČSD 324.316. It was impressed into DRG in 1939 and withdrawn in 1943. It is doubtful if it ever saw any use with PKP.
