Donetz Railway A1 to A11
Russian Empire 1878 11 produced
In 1878, Borsig built eleven 2-4-0 passenger locomotives for the Donetz Railway in the Russian Empire, in the part that is now the contested part of Eastern Ukraine. They had drivers with a diameter of 1,600 mm and cylinders of 410 by 560 mm. In these dimensions, and also in the boiler heating surfaces, they were fairly similar to the Prussian P 1 that was also built by Borsig. Up to the year that followed the delivery of these locomotives, Borsig had delivered a total of 3,700 locomotives, of which 718, the second largest portion, had gone to Russia.
