Data from "Heavy Twelve-wheel Locomotives for the Great Northern", Railroad Gazette, Volume XXX, No 1 (7 Jan 1898), table, p. 5; and CB&Q Assorted Early Steam Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Rail Data Exchange. (Thanks to Chris Hohl for his 11 March 2016 email correcting the original coal capacity.) Works numbers were 4504-4505 in May 1891 and 4525 in June.
A large "decapod" (although without the lead axle usually associated with that name) probably used for switching and helper service. Sported a Belpaire boiler fitted with tubes of an unusual diameter (2 1/2" or 63.5 mm).
The original tender weighed 29,000 lb (13,154 kg) empty and 74,000 lb (33,566 kg) loaded with 3,480 US gallons (13,172 litres) of water and 8 tons(7.3 metric tons) of coal.
The trio was renumbered by the Chicago, Burlington & Quincy in 1904 and worked until they were retired in 1916.
