Prussian G 4.2

In 1882 the first two prototypes were built by Henschel; but it was 1885 before series production commenced. Production continued until 1899, but in 1903 there was an order for the East Prussian Southern Railway (Ostpreußische Südbahn, OS). A total of 780 locomotives of this type were delivered to Prussian railways. The compound locomotives proved to be more economical and more powerful than the two-cylinder-simple locomotives. The G 4.2 was used in freight train service on longer routes. After the end of World War I, six G 4.2 went to Italy (as FS 272.005–010) as reparations. The Polish State Railways also received locomotives of this type and classified them as Th3. In 1920, The Deutsche Reichsbahn reallocated a G 4.2 to the Schwerin Division, where it was renumbered 406 in the Grand Duchy of Mecklenburg Friedrich-Franz Railway list.
