▚ Through the Rockies
The Denver & Rio Grande was built starting in 1870 as a narrow-gauge line to conquer the Colorado mountains — the famous "Thru the Rockies, not around them." It fought the Santa Fe for the Royal Gorge and built some of the most spectacular mountain railroading in North America.
▚ Standard gauge and the Moffat Tunnel
The road standard-gauged its mainline and, in 1934, opened the 6.2-mile Moffat Tunnel under the Continental Divide, shortening the Denver–Salt Lake route dramatically. Its tunnel-motor and SD40T-2 fleet worked heavy grades in gold-and-black.
▚ The little railroad that bought the big one
In 1988, in a famous reversal, the much smaller Rio Grande's holding company bought the giant Southern Pacific — and took the SP name. The combined system was absorbed into Union Pacific in 1996.
▚ On this layout
Rio Grande is a big HO roster here — ALCO PA/PB passenger units, F3/F7/F9 cab units, SD40T-2 tunnel motors, SD45s, and GP40-2s, all in aspen gold and black. Some of the finest brass F-units on the layout wear Grande gold.
