There are two persistent myths that show up in almost every book or article which mentions the role of the White Pass & Yukon Route in the building of the Alcan Highway during the Second World War. The myths concern the eleven new USATC S118 Class locomotives that the United States Army Transportation Corps brought to the WP&YR in 1943. Myth No. 1 is that they were converted from gauge to gauge by the WP&YR shops in Skagway, Alaska. Myth No. 2 is that they were built for Iran and diverted to the WP&YR.
