The Ely-area copper properties were further merged in 1904, forming the Nevada Consolidated Copper Company, and the Nevada Northern Railway was incorporated on June 1, 1905, to build a line connecting the Nevada Consolidated mines and smelter to the national rail network. The task of building the new railroad was contracted to the Utah Construction Company, which began work on September 11, 1905. Construction began at Cobre, where the Nevada Northern connected with the Southern Pacific, and proceeded southward. The line was finished a year later, its completion marked by a two-day celebration in Ely. The railroad's symbolic final spike—made of local copper—was driven by Requa in Ely on September 29, 1906, which was designated as Railroad Day. To celebrate the new railway, a ball was held inside the Northern building, which was still under construction at the time.
