Royal Württemberg State Railways (Königlich Württembergische Staats-Eisenbahnen) had considerable number of class F 0-3-0 freighters with single-expansion steam engines, built by Maschinenfabrik Esslingen between 1864 and 1880. From 1890 onwards they were supplemented by more powerful compounds with the same axle arrangement and steam pressure increased from 9 to 12 bar. Until 1892 Esslingen built thirty such locomotives, classed Fc; they were assigned service numbers 611 through 640 and all had individual names. Production was resumed in 1896 and until 1908 further 87 examples were built, with steam pressure increased to 14 bar. These were assigned service numbers 641 through 731 with gaps (see below) and had no individual names. Eight more were assembled by Staatsbahnwerkstätte Esslingen railway works: two in 1907 (717 and 718), two in 1908 (724 and 725) and four in 1909 (732 through 735). This gives 125 locomotives in all. They were typically coupled with two-axle 2T10 tenders.
In early 1920s 98 engines of this type were still in use, assigned to four regional managements. In 1925 DRG classed 65 of them 538; this number included eleven of the earlier variant and 54 of the later. Last were withdrawn in 1929 and none has been preserved. According to TB vol. 1, Polish state railways took over 21 examples; however, LP lists only twenty classed Th102 in 1925. Possibly one engine was withdrawn earlier. Assignment of service numbers to individual examples is not known. These obsolescent and untypical locomotives were all withdrawn before 1927.
