Bullfrog Goldfield Railroad
The Bullfrog Goldfield Railroad (BGRR) was a 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 and the Southern Pacific Railroad.
