>>1100391There aren't a lot of 2-4-0s left here, either. While the big Class one railroad locomotives are kind of rare, there are quite a few smaller locomotives on small railroads and in logging and industrial applications that soldiered on a decade or two after the big railroads had abandoned steam power. Logging railroads had some creative solutions to getting a lot of tractive effort into a relatively small package. Pic is Black Hill Central Railroad's 2-6-6-2t, a Mallet tank engine.
