By Oct. 1906, Heney had retired and decided to sell his Copper River right-of-way to the Alaska Syndicate that consisted of M. Guggenheim & Sons and J.P. Morgan & Co. However, he returned to work for Daniel Guggenheim on the Copper River railway in 1907 after the destruction of the winter storm. Guggenheim had decided Cordova was a better starting point. The railroad was built by the Kennecott Corporation (now part of the Alaska Syndicate) between 1908 and 1911 to take copper ore from Kennecott, Alaska to Cordova, Alaska, a distance of 315 km (196 mi).
