Charles Kratz in Drury (1993) says of these 25 engines : "They were fast and powerful and they changed the C&EI did business."
Based on the light USRA design, but there are some small, slight differences. Retired 1940-1950..
These Mikes represent the difficulty in any effort at standardization as represented by the USRA series. Although competent engines, they don't signify a significant improvement over either USRA 2-8-2.
