The Shay locomotive, named after Ephraim Shay was a workhorse where heavy loads and steep grades were involved. No. 2645 had 9 owners from 1913 to 1988 when it was purchased by the Yosemite Mountain Sugar Pine Railroad at Fish Camp, California. Its advantage over other steam locomotives of the day was a stepped-down gear ratio and a drive shaft connected to several pairs of wheels through universal joints, as shown here. Note the glowing firebox top center. This locomotive was converted to be powered by oil instead of wood.
