GE 45-tonner #7324 was built in 1942 (builder number 15244) for the U.S. Army.  The Alaska Railroad acquired it in 1974 and gave it to the Museum of Alaska Transportation and Industry in 1983.

GE 45-tonner #7331 was built for the U.S. Army in 1941 (builder number 12985) and the Alaska Railroad inherited it in 1974.  It was sold to CCPR in 1983 (along with 7249 and 7356).

Ed took this photo of two GE 45 ton units in either the summer of 1976 or '1977 at the Anchorage Shops.
