The Carson and Colorado Railway was a U.S. 3 ft (914 mm) narrow gauge railroad that ran from Mound House, Nevada, to Keeler, California, below the Cerro Gordo Mines.

[3] Darius Ogden Mills (part owner) was once quoted saying "Either we built the line 300 miles too long, or 300 years too early!"

[2] From the time of the purchase until 1905, all of the C&C’s freight traveled over the V&T's trackage from Mound House to Reno, and vice versa.

[4] The northern 140 miles (230 km) from Mound House to Mina, Nevada was converted to 4 ft 8+1⁄2 in (1,435 mm) standard gauge in 1905; and the remaining C&C was merged into the Southern Pacific's 3 ft (914 mm) narrow gauge subsidiary, the Nevada and California Railroad.

Portions of the line were abandoned in the 1930s and the 1940s, and the last narrow gauge common carrier made its final run on April 29, 1960.

The following were towns or stops along the line:[8][9] In Independence, California, a non-profit group re-incorporated the Carson and Colorado Railway.
