The 2-10-0 arrangement was a very popular one in Germany. The first were built by the individual state railways from 1915 to 1918, and these later became the DRG BR58. The DRG then produced a number of standard classes of 2-10-0s: the heavy 3-cylinder BR44 (1753 built), the two-cylinder version BR43 (35 built), and the lightweight BR50 (3164
If Meyer's index is less than 2.2 then the ratio of UTS to BHN is 0.36. If Meyer's index is greater than 2.2, then the ratio increases. [1] The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten ...

It had a parallel boiler and round-topped firebox.While the 2-8-0 had a narrow firebox, the 2-10-0 had a wide firebox placed above the driving wheels. This arrangement was common in the United States (e.g. the USRA 0-8-0) but unusual in Britain, where wide fireboxes were usually used only where there was a trailing bogie, e.g. in 4-4-2 and 4-6-2 types.
