Waterloo Mining Railroad
The Waterloo Mining Railroad, also known as the Calico Railroad or Daggett-Calico Railroad, was a 3 ft (914 mm) narrow gauge railroad built to carry silver ore from the mines in the Calico Mountains north of Calico to the mills located at Elephant Mountain near Daggett, California, from 1888 to 1903. The American Borax Company leased, and later bought, a small length of the railroad to use for their borax mining operations near Lead Mountain in 1901, and the line managed to last for about another six years afterwards.
