Track on 5 December 1907:
The Bullfrog Goldfield Railroad (BGRR) was a private single-track standard-gauge steam railroad lying just inside and about midway of the southwestern State line of Nevada. It was incorporated in 1905 to provide an outlet from the mining section near Beatty to the north over the lines of the Tonopah and Goldfield Railroad Company and the Central Pacific Railway Company.
The main line of the Bullfrog Goldfield Railroad Company extended from Beatty 78.95 miles (127.06 km) in a general north-northwesterly direction to Goldfield. A 5.83 miles (9.38 km) long branch line, ran westward from Beatty to Rhyolite. The total road mileage owned was thus 84.78 miles. Yard tracks and sidings to an aggregate of 7.70 miles (12.39 km) brought the total owned mileage to 92.48 miles (148.83 km). The Bullfrog Goldfield Railroad Company owned no terminal facilities, as such, but used the station and yard facilities at Beatty belonging to the Las Vegas & Tonopah Railroad Company.
The Bullfrog Goldfield Railroad Company was incorporated September 1, 1905, under the general laws of Nevada, for a period of 50 years, by interests connected with the Tonopah and Goldfield Railroad Company and apparently connected with the Tonopah Mining Company. The purpose was to build a line from the southern terminus of the line of the Tonopah and Goldfield Railroad Company, at Goldfield, southward to the mining field in which Beatty and Rhyolite were the principal camps, thereby giving an outlet to this mining territory over the line of the Tonopah and Goldfield Railroad Company to the Central Pacific Railway Company at Tonopah in competition with the lines of the Las Vegas & Tonopah Railroad Company and the Tonopah and Tidewater Railroad Company, both of which had connections southward.
Construction was by the Amargosa Construction Company under contracts dated March 20, 1906, and December 27, 1907. The mileage shown above is that appearing in the records of the Bullfrog Goldfield Railroad Company. Construction commenced in the early part of 1906, and the line was completed, equipped, and opened for operation in May, 1907, from which date the Amargosa Construction Company operated the road until January 1, 1908.
