Yosemite Valley Railroad was incorporated in 1902, constructed from 1905 to 1907, and abandoned and scrapped in 1945 and 1946.

Yosemite Valley Railroad Caboose No. 15 is an excellent example of a wooden, short-line railroad freight caboose. It was operated on the line between El Portal and Merced.

Yosemite Valley Railroad Caboose No. 15 is the second caboose to bear that number on this railroad. The best available evidence indicates that it was added to the Yosemite Valley equipment roster about 1922, although the caboose itself may be much older. From whom the railroad purchased it, and whether new or second-hand, is unknown, but it is presumed to have been obtained second-hand by the Yosemite Valley Railroad.
