Coaches #112 "ORVILLE"(top photo); #125 "KEYSTONE" (center photo); and #133 "ADDIE CAMP" (bottom photo) were originally part of a series of interurban passenger equipment built by the American Car Company for the Oregon Electric Railway in 1913. Some of the equipment from this series was, in turn, sold to the Pacific Great Eastern Railway in British Columbia, Canada, where they were used until the mid-1960s. The Black Hills Central purchased the 112, 125, 133, 140, 144, and several other cars in the early 1970s. The Addie Camp features its authentic interior with few changes, while the Black Hills Central staff completely restored the Orville in 1997. The Keystone was returned to service after its complete restoration in 2004.
