The line was born of the Klondike Gold Rush of 1897. The most popular route taken by prospectors to the gold fields in Dawson City was a treacherous route from the port in Skagway or Dyea, Alaska, across the mountains to the Canada–US border at the summit of the Chilkoot Pass or the White Pass. There, the prospectors were not allowed across by Canadian authorities unless they had sufficient gear for the winter, typically one ton of supplies. This usually required several trips across the passes. There was a need for better transportation than pack horses used over the White Pass or human portage over the Chilkoot Pass. This need generated numerous railroad schemes. In 1897, the Canadian government received 32 proposals for Yukon railroads, and most were never realized.
