The Denver and Rio Grande Western Railroad, often shortened to Rio Grande, D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a 3 ft narrow-gauge line running south from Denver, Colorado, in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic.

Its county seat and largest city is Salt Lake City, the state capital. The county was created in 1850. Salt Lake County is the 37th most populated county in the United States and is one of four counties in the Rocky Mountains to make it into the top 100. Salt Lake County is the only county of the first class in Utah – under the Utah Code is a county with a population of 700,000 or greater.
Wasatch County is a county in the U.S. state of Utah. As of the 2010 United States Census, the population was 23,530. Its county seat and largest city is Heber City. The county was named for a Ute Native American word meaning mountain pass or low place in the high mountains.

The Wasatch Range or Wasatch Mountains is a mountain range in the western United States that runs about 160 miles (260 km) from the Utah-Idaho border south to central Utah. It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region. The northern extension of the Wasatch Range, the Bear River Mountains, extends just into Idaho, constituting all of the Wasatch Range in that state.
The Denver and Salt Lake Railway (D&SL) was a U.S. railroad company located in Colorado. Originally incorporated in 1902 as the Denver, Northwestern and Pacific (DN&P) Railway, it had as a goal a direct connection of Denver, Colorado, with Salt Lake City, Utah. It underwent numerous reorganizations throughout its financially troubled history and by the time the company was acquired in 1931 by the Denver and Rio Grande Western Railroad, it had advanced only as far as Craig, Colorado. After the acquisition the line was connected to the D&RGW main, and the eastern half of the line was used to give the D&RGW a more direct route to Denver. The portions of the railroad still in use today are known as the Moffat Tunnel Subdivision of Union Pacific Railroad's Central Corridor. Amtrak’s California Zephyr service from Denver to Glenwood Springs follows much of the old D&SL route.
Cajon Pass is a mountain pass between the San Bernardino Mountains to the east and the San Gabriel Mountains to the west in Southern California. Created by the movements of the San Andreas Fault, it has an elevation of 3,777 ft (1,151 m). Located in the Mojave Desert, the pass is an important link from the Greater San Bernardino Area to the Victor Valley, and northeast to Las Vegas. The Cajon Pass area is on the Pacific Crest Trail.
Parleys Canyon is a canyon located in the U.S. state of Utah. The canyon provides the route of Interstate 80 (I-80) up the western slope of the Wasatch Mountains and is a relatively wide, straight canyon other than near its mouth. The mountain pass at the top of the canyon is known as Parleys Summit. With an elevation of 7,120 feet (2,170 m), the pass is the highest point along I-80 in the state of Utah. Both features are named for Parley P. Pratt, an early settler of the Salt Lake Valley and leader of the Church of Jesus Christ of Latter-day Saints who surveyed the area to find a better transportation route through the Wasatch Mountains than the previous route which traversed Emigration Canyon.
The Heber Valley Railroad (HVRX) is a heritage railroad based in Heber City, Utah. It operates passenger excursion trains along a line between Heber City and Vivian Park, which is located in Provo Canyon. The HVRX carries over 110,000 passengers a year.
Thistle is a ghost town in Spanish Fork Canyon in southeastern Utah County, Utah, United States. During the era of steam locomotives, the town's primary industry was servicing trains for the Denver and Rio Grande Western Railroad. The fortunes of the town were closely linked with those of the railroad until the changeover to diesel locomotives, when the town started to decline.
Interstate 70 (I-70) is a mainline route of the Interstate Highway System in the United States connecting Utah and Maryland. The Utah section runs east–west for approximately 232 miles (373 km) across the central part of the state. Richfield is the largest Utah city served by the freeway, which does not serve or connect any urban areas in the state. The freeway was built as part of a system of highways connecting Los Angeles and the Northeastern United States. I-70 was the second attempt to connect southern California to the east coast of the United States via central Utah, the first being a failed attempt to construct a transcontinental railroad. Parts of that effort were reused in the laying out of the route of I-70.
Interstate 80 (I-80) is a part of the Interstate Highway System that runs from San Francisco, California, to Teaneck, New Jersey. The portion of the highway in the US state of Utah is 197.51 miles (317.86 km) long through the northern part of the state. From west to east, I-80 crosses the state line from Nevada in Tooele County and traverses the Bonneville Salt Flats—which are a part of the larger Great Salt Lake Desert. It continues alongside the Wendover Cut-off—the corridor of the former Victory Highway—US Route 40 (US-40) and the Western Pacific Railroad Feather River Route. After passing the Oquirrh Mountains, I-80 enters the Salt Lake Valley and Salt Lake County. A short portion of the freeway is concurrent with I-15 through Downtown Salt Lake City. At the Spaghetti Bowl, I-80 turns east again into the mouth of Parleys Canyon and Summit County, travels through the mountain range, and intersects the eastern end of I-84 near Echo Reservoir before turning northeast toward the Wyoming border near Evanston. I-80 was built along the corridor of the Lincoln Highway and the Mormon Trail through the Wasatch Range. The easternmost section also follows the historical routes of the first transcontinental railroad and US-30S.
Tucker is a ghost town located near the east end of the Spanish Fork River in Utah County, Utah, United States 7 miles (11 km) below Soldier Summit on U.S. Route 6. It was once an important loading point and construction camp on the Denver and Rio Grande Western Railroad (D&RGW). After the town was abandoned, the state of Utah used the town site for a rest area. In 2009, the site was buried as part of a project to re-align a portion of US-6's western approach to Soldier Summit. To honor the town, the state of Utah built a replacement rest area about 2 miles (3.2 km) downstream from Tucker, called the Tie Fork Rest Area.
Colton is a ghost town located near the southeastern edge of Utah County, Utah, United States, approximately 6 miles (9.7 km) south of Soldier Summit. Formerly a busy railroad junction on the Denver and Rio Grande Western Railroad, Colton is a landmark on U.S. Route 6 between the cities of Spanish Fork and Price.

The Central Corridor is a rail line operated by the Union Pacific Railroad from near Winnemucca, Nevada to Denver, Colorado in the western United States. The line was created after the merger with the Southern Pacific Transportation Company by combining portions of lines built by former competitors. No portion of the line was originally built by the Union Pacific; in fact, some portions were built specifically to compete with the Union Pacific's Overland Route. The line is known for significant feats of engineering while crossing the Wasatch Mountains of Utah and the Rocky Mountains of Colorado. The line features numerous tunnels, the longest and highest of these is the Moffat Tunnel.
The California Zephyr is a passenger train operated by Amtrak between Chicago and the San Francisco Bay Area, via Omaha, Denver, Salt Lake City, and Reno. At 2,438 miles (3,924 km), it is Amtrak's longest daily route, and second-longest overall after the Texas Eagle's triweekly continuation from San Antonio to Los Angeles, with travel time between the termini taking approximately 511⁄2 hours. Amtrak claims the route as one of its most scenic, with views of the upper Colorado River valley in the Rocky Mountains, and the Sierra Nevada. The modern train is the second iteration of a train named California Zephyr; the original train was privately operated and ran on a different route through Nevada and California.
