On display at the Union Depot Railroad Museum in Mendota, Illinois, is Burlington Route class O-1A Mikado No. 4978. The building also houses the Amtrak depot. Though of modest dimensions compared with many other 2-8-2s, the veteran Mikes of class O-1A were among the last steam engines to be operated by the CB&Q. I took the photograph on June 17, 2018.
