Burlington K-2 class 4-6-0 637 was built by Rogers Locomotive & Machine Works in November 1892 as Burlington & Missouri River 309. In 1949 this locomotive was refitted with a diamond stack for exhibition at the Railroad Fair Pageant in Chicago. It was retained for exhibition purposes until given to the City of Aurora for display. It was eventually donated to the Illinois Railway Museum. This trip was sponsored by the Illini Railroad Club on Labor Day weekend, 1956. The excursion featured CB&Q 4000 and CB&Q 537. After leaving Aurora with the excursion, CB&Q 637 took water at an unknown location, possibly the Sheridan, Il depot.
