From the G 10 to the 057.
The good experience with the Prussian class T 16.1 (later class 94.5-17) freight tank locomotive with five coupled axles prompted the Royal Prussian Railroad Administration to order a steam locomotive with this wheel arrangement and with a tender.
The firm Henschel in Kassel developed such a locomotive that was designated as the class G 10 on the Prussian Railroad. Following thoughts about standardization, a Garbe design boiler was chosen; this design had already given extremely good results on the class P 8 (later class 38.10-40). With this boiler, the G 10 reached a maximum speed of 60 km/h / 38 mph with an indicated performance of 1,100 horsepower. The first locomotives were delivered to the Prussian State Railroad in 1910.
By 1925, there were a total of 2,589 units of the G 10, which were integrated into the German State Railroad Company's (DRG) motive power roster as the class 57.10-35. During repairs several locomotives were equipped with the similar boilers from the class 38, which however differed in the number of steam and sand domes. After 1945, the roster of class 57.10-35 locomotives was greatly decimated. In 1950, there were only 391 units on the DB, on the DR (East Germany) approximately 125 units that were all assembled in the DR's Schwerin District.
A handful of DB locomotives survived into Era IV as the class 057. Today, there are still 2 original class 57 locomotives and 6 locomotives of similar design preserved by other European railroads.
