>>1449197>All steam engines in central Europe built during the 1930s and 40s look German. Why is that?I don't know, but if I had to guess it's probably either due to designs and blueprints being licensed out or sold to other manufacturers in nearby countries.
It could also be knockoff designs/copies in the case of post war locomotives. German designs/patents were practically free game after WWII resulting in lots of Soviet bloc countries producing cheap copies of German manufactured goods, and I wouldn't be surprised if locomotives were also copied and built.
Could also be a result of pre-WWI Imperial Germany's influence. If you look at countries that were once part of the British empire, they are very similar looking to British steam locomotives, pic related.
