DRG 17 408, former 3318 (Maffei 2413/1904), RAW München-Freimann, May 22, 1941. This locomotive was later rebuilt with steam superheating and survived WWII, but saw no post-war service and was written off in December 1946.

Among German locomotives acquired by PKP after WWI, the majority were of Prussian origin. Railways of other German lands, however, also had their contributions – far less numerous, but by no means less interesting. An example is Among oddities and rarities in the PKP inventory after WWI was a single S 3/5 N of Bavarian state railways (Königlich Bayerische Staatseisenbahnen). Between 1903 and 1907, J.A.Maffei of Munich delivered 39 engines of this type – four-cylinder compounds running on saturated steam, numbered 3301 through 3340 (No. 3329 was the prototype of class S 3/5 H with Schmidt-type superheater, of which thirty examples were eventually built). With 1870 mm drivers and maximum speed of 110 km/h, they served as light express locomotives and were assigned to Munich I and Nuremberg depots. Later engines of this type, built from 1904 onwards (starting from 3311) had boilers shortened by 300 mm; with boiler pressure increased from 14 to 16 bar, they were slightly heavier, but effect on performance was marginal.
After WWI, twenty locomotives of this type were impressed into DRG as class 174. Between 1924 and 1925 most were rebuilt and fitted with steam superheaters, but their designation was not changed. Withdrawals started in early 1930s and only seven engines, all with ‘short’ boilers and superheaters, survived until WWII. The last one, 17 415 (former 3326, Maffei 2421/1905), was withdrawn in January 1948. French railways took over eighteen examples, which were impressed into Chemins de Fer de l’Est (thirteen, numbered XI.3351 through 3363) and Chemins de Fer d’Alsace-Lorraine (five, class S9, numbered 982 through 986 – ‘original’ class S9 comprised eighty De Glehn locomotives, built from 1906 onwards). Polish state railways received one engine of this type, former No. 3333 (Maffei 2601/1907). Initially it was designated P8Bw, the superscript standing for ‘Bawaria’, or Bayern, although had nothing to do with class P8, apart from axle arrangement. In 1925 it was re-designated Ok103-1. It seems probable that this untypical locomotive had been brought from France for evaluation purposes (just like the single Prussian G12, later Ty1, or class C of the Königlich Wüttembergische Staatseisenbahn, which became Om101), but this is just a conjecture. Ok103-1 still remained in the PKP inventory in 1927, but disappeared before 1931. No details concerning her service are available. Not a single example of this beautiful engine has survived until today.
