This was C&NW Weekend at the Illinois Railway Museum, where all the C&NW locomotives on museum property were given a chance to run trains on the mainline. The museum also hosted the C&NW Historical Society as part of its annual convention, and Union Pacific even sent UP 1995 for display! Here, CRIP 4506, which today is "patched" as CNW 4160, has just put the caboose train away and is returning to the front of the museum, passing by an old rail diesel coach (RDC), which was built as CNW 9933.
