The unusual Galloping Goose trains of the 1950's


According to wikipedia:

Galloping Goose is the popular name given to a series of seven railcars (officially designated as "motors" by the railroad), built in the 1930s by the Rio Grande Southern Railroad (RGS) and operated until the end of service on the line in the early 1950s. They were derived from full-sized automobiles.

Originally running steam locomotives on narrow gauge railways, the perpetually struggling RGS developed the first of the "geese" as a way to keep its contract to run mail into towns in the Rocky Mountains in Colorado.
