This is a video about the improvements White Pass & Yukon Route made between 1967 and 1969. This also includes the Roundhouse Fire which happened on October 15, 1969.
The #72's boiler was scrapped in 1974 and the rest of her remains were later sold to Silver Dollar City as a source of spare parts for the #70 and #71 who were also sold to Silver Dollar City. SDC later became Dollywood in 1986.
The Cantilever bridge that was closed should be rebuilt and reused again. Restoration must be put on to the Cantilever bridge at dead horse gulch. I think a good name is the Dead Horse Trestle. If I designed a new locomotive for the White Pass and Yukon railway, I would make it a CoCo narrow gauge diesel locomotive that would have cabs at the front and back and it would be made of light metal’s and a super strong engine and it would be full width. The cabs on both sides will look like the Alco locomotive’s fronts but instead they would be full flat on the top and rounded at the front’s.
