Chicago, Burlington and Quincy 5632 was an O-5B class 4-8-4 “Northern” built in the CB&Q's shops in August 1940. It was used to pull mainline passenger and freight trains before it eventually became famous for pulling a plethora of excursion trains for the CB&Q's steam excursion program. By the time the program ended in 1966, No. 5632 was disassembled for an unfinished overhaul, and was subsequently sold to Chicago area railfan Richard Jensen.

The locomotive was moved inside a Chicago and Western Indiana Railroad (C&WI) roundhouse for restoration. In 1969, No. 5632 was evicted from the roundhouse and illegally moved to a scrapyard. Upon entry, the locomotive derailed on a curve, resulting in its scrapping in 1972 and a subsequent lawsuit between Jensen and the C&WI.
