White Pass & Yukon Route 73 is a narrow-gauge 2-8-2 "Mikado" type steam locomotive. It was built by the Baldwin Locomotive Works for the White Pass and Yukon Route in May 1947. [3] [4] After retirement on June 30, 1964, the locomotive was moved to Bennett, British Columbia, in 1968 for static display. In 1979, the locomotive was moved again to Whitehorse, Yukon, this time to be restored to operating condition. Restoration was completed in 1982, and the locomotive has been back in service since then. As of 2010 it was the larger of two operating steam locomotives on the line.
