Denver and Salt Lake Railway
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.

Denver and Rio Grande Western Railroad
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.
During the late 1800s the D&RG made extensive use of consolidations (engines with a 2-8-0 wheel arrangement). This drawing, of an unusual wheel arrangement, was titled "Standard Consolidation Engine," 1881.
Over the course of decades, D&RG consolidations were subjected to various modifications. In the 20th century, diamond stacks gave way to straight stacks, box headlights were replaced with round ones, decorative trim disappeared from the domes, and wooden pilots (cowcatchers) were replaced with steel ones.
