he Rio Grande Southern Railroad holds a storied history in southwest Colorado, leaving an indelible mark on the region's development. Established in the late 19th century, the RGS was envisioned as a vital transportation link between the mining towns of Rico, Telluride, and Durango, as well as connecting them to broader markets. Otto Mears, a prominent figure in Colorado's transportation history, played a pivotal role in the inception and expansion of the RGS. His vision and entrepreneurial spirit were instrumental in securing financing and navigating the challenging terrain of the San Juan Mountains, where the railroad would operate. Based in Ridgway, Colorado, in the north, the RGS spanned a 162 miles on a meandering route to Durango in the south. The narrow gauge shortline connected with the mighty Denver, Rio Grande & Western's slim gauge empire at both ends of its run.

The Rio Grande Southern eked out a living hauling freight, mail, and passengers, but was never a financial success. It's surviving spirit was epitomized by the development of the "Galloping Goose" railcars. These unique, home-built, self-propelled vehicles were adapted from traditional freight cars and automobile parts to traverse the rugged mountainous terrain efficiently, with minimal labor costs. The Geese not only facilitated transportation of passengers and freight, but also became emblematic of the railroad's ingenuity and adaptability. Despite facing numerous challenges, including financial difficulties and the decline of mining in the area, the RGS persevered for several decades, serving as a lifeline for remote communities and contributing significantly to the region's economic and social fabric.

However, by the mid-20th century, advancements in transportation and shifting economic landscapes led to the decline of the RGS. The railroad ceased operations in 1952, marking the end of its storied era. Nevertheless, the legacy of the Rio Grande Southern Railroad lives on through preservation efforts by organizations like the Galloping Goose Historical Society and the Ridgway Railroad Museum, which celebrate the shortline's history and its enduring impact on the communities and landscapes of southwest Colorado. Many steam locomotives, some rolling stock, and nearly all of the Galloping Geese have been preserved in various locations.
