Steam locomotive class 35.10 of the German Reichsbahn. Drive on two axles of the tender and via a cardan shaft on all three driving axles of the locomotive. With the introduction of the computer-based numbering system at the German Reichsbahn, the locomotives formerly designated as class 23.10 received the new class designation 35.10. The locomotives were a development result from the two prototype locomotives 23 001 and 23 002. The locomotives of class 35.10 were particularly popular among operating personnel due to their low coal consumption and smooth running.
