Rio Grande Southern Motor #6. One of the lesser-known members of the Rio Grande Southern Galloping Goose family is this little critter, which currently resides at the Colorado Railroad Museum in Golden, CO. Designed primarily for maintenance of way (MOW) operations, RGS Motor #6 was built in 1934, mostly out of parts that remained when the "Goose" prototype, Motor #1, was scrapped. Her front body and engine were originally from a Buick automobile, and her rear stake-truck body was fabricated by the RGS shops. Only the rear truck was powered, with the driveshaft powering the front axle and the rear axle powered by the chain-drive which is obvious in this image. Like the other "geese", she had a large, cow-catcher-type pilot, and typically carried a plow during winter operations In 1942, this unit was re-built with a Pierce Arrow body and engine and that's the configuration you see today.
