Skagway is home to the "White Pass" railroad. It was built to bring supplies to the klondike Gold Rush territory some 60 miles inland. The railroad terminated at the town of White Horse in the Yukon territory, Canada.

The White Pass & Yukon railway was built in 1898 during the Klondike Gold Rush, this narrow gauge railroad is an International Historic Civil Engineering Landmark, a designation shared with the Panama Canal, the Eiffel Tower and the Statue of Liberty.

The WP&YR suspended operations in 1982 when Yukon’s mining industry collapsed due to low mineral prices. The railway was reopened in 1988 as a seasonal tourism operation and served 37,000 passengers. Today, the WP&YR is Alaska’s most popular shore excursion carrying over 390,000 passengers during the 2012 May to September tourism season operating on the first 67.5 miles (Skagway, Alaska to Carcross, Yukon) of the original 110 mile line.
