History of the D&RGW K-37 Class ~ Massive 3ft Gauge Mikados (Obscure Offerings Ep. 16)

The K-37s were the Rio Grande's final 2-8-2 'Mikados', notable for their strange use of boilers and tenders from standard gauge 2-8-0s. Indeed, I think they look a little too big for 3ft gauge. Ten of them were built and eight have been preserved, with 491 possibly being the most well-known survivor due to Hyce showing her off in several of his videos, and said videos introduced me (and probably several other railfans) to the K-37 class.
