The Caribou Creek served as the Alaska Railroad's business car until 1972 when it was replaced by the Denali. Today, the Caribou Creek resides in Elbe, Washington as part of the Mt. Rainier Scenic Railroad.
Caribou Creek was built by American Car and Foundary in 1917. It was rebuilt by International Railway Car and Equipment Company. The Alaska Railroad purchased it in October of 1947 from the Bureau of Mines.

The consist was the cut down "buffalo hunting car", two former SP commuter coaches and the former Alaska Railroad "Caribou Creek" renamed "Deschutes River". The "Deschutes River" was seeing its first service on the Mount Rainier Scenic and your editor noted that the gold stripes were not completed when I photographed it in Tacoma prior to the start of the trip but were completed when photographed when enrout to Centralia.
