CNW caboose 10958 is on the tail end of a northbound train about to depart Jefferson Jct. for Clyman Jct. Jefferson Jct. was the crossing of CNW's Milwaukee-Madison line and the Fond Du Lac-Janesville line. The Milwaukee-Madison segment was gone (except for some short stubs at the Jct.)when this photo was taken. Today, only the Clyman Jct.-Jefferson portion of the Fond Du Lac-Janesville line remains in service.
