Rio Grande Scenic Railroad, Heritage railway in Alamosa, Colorado, US

The Rio Grande Scenic Railroad was a heritage railway that ran standard-gauge trains from Alamosa over La Veta Pass in the Sangre de Cristo Mountains and east to Antonito, where passengers could connect with the narrow-gauge Cumbres and Toltec. It operated from 2006 to 2019 as a subsidiary of the San Luis and Rio Grande Railroad, using steam locomotives on many trips between 2007 and 2013.

The Denver and Rio Grande Railroad, chartered in 1870, crossed La Veta Pass by narrow gauge in 1877 and reached Alamosa on July 6, 1878; it converted the pass and Creede lines to standard gauge around 1900. Iowa Pacific Holdings, which bought the San Luis and Rio Grande Railroad in December 2005, established the Rio Grande Scenic Railroad in 2006. Excursions ended in 2019 after a wildfire damaged the Fir Concert Grounds and the parent company entered Chapter 11 bankruptcy.

The railway staged music performances at Fir Concert Grounds, featuring performances from The Nitty Gritty Dirt Band, Ricky Skaggs and Asleep at the Wheel.

Most passengers boarded at the Alamosa station, with connections possible to other rail lines at Antonito. Visitors should have brought warm clothing since journeys passed through high-altitude alpine regions with cool temperatures.

Steam excursions between 2007 and 2013 were usually hauled by one of two locomotives: Ex-Southern Pacific 2-6-0 "Mogul" No. 1744, withdrawn early over firebox problems, and Ex-Lake Superior and Ishpeming 2-8-0 "Consolidation" No. 18, the only other steam engine the SLRG ran. When the line was liquidated, locomotives and rolling stock went to the Colebrookdale Railroad and the Reading Blue Mountain and Northern Railroad in Pennsylvania.
