With the line into Utah complete, the D&RG system consisted of a narrow gauge main line from Denver to Ogden, passing through or over Colorado Springs, Pueblo, the Royal Gorge, Salida, Marshall Pass, Gunnison, the Black Canyon of the Gunnison, Montrose, Grand Junction, Green River, and Salt Lake City. It included numerous branches, but only three west of Grand Junction - to Pleasant Valley, Bingham Canyon, and Little Cottonwood Canyon. The main line began by following the valley of the Grand (Colorado) River west out of Grand Junction, but curved away at Mack to avoid Ruby Canyon. Some steep grades and sharp curves carried the original line over the highlands north of the river, crossing the state line and continuing southwesterly and westerly to Green River, Utah. Curving northwest around the Beckwith Plateau, the railroad crossed the Price River at Woodside, where it began to follow that river through its valleys and canyons. Almost immediately, due to flooding, the railroad had to be removed from the canyon between Grassy Trail (south of Cedar) and Farnham (southeast of Wellington), though it remained alongside the river from Grassy Trail southeast to Woodside until bypassed by the present standard gauge alignment. Continuing on, the line passed through the Price Canyon, including the Castle Gate rock formation, as it rose to the top of the Wasatch Range at Soldier Summit. The Spanish Fork Canyon took the line down into the Utah Valley, with some 4% grades near the top before it met the earlier U&PV at Tucker. Through the Utah Valley and adjacent Salt Lake Valley, connected by the Jordan Narrows, the D&RGW's line closely paralleled a UP line, serving many of the valleys' populated areas. The final stretch generally followed the Great Salt Lake's shore to Ogden, where it connected to the Central Pacific Railroad.
