Chicago, Burlington & Quincy 0-6-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class I (Locobase 5452)

Data from a locomotive diagram published on Vernon Beck's website -- [] (accessed 22 March 2003). See also "Class I Locomotive - Chicago, Burlington & Quincy", Railroad Gazette, Volume 21 (11 November 1889), p. 718 and (13 December 1889), pp. 816-817; and E E R Tratman, "Tank Locomotives", Official Proceedings of the Western Railway Club (Chicago: W F Hall Printing Company, 1905), pp. 350. Rupert Gamlen's roster (accessed 29 March 2003) tells us that five of these were built from 1889-1893.

Corbin & Kerka (1960) tell us that these Belpaire-boilered oddities were designed to operate in either direction. The three drivers on each side were separately equalized and neither was interconnected with the swing-bolster trailing truck. The 0-6-2T arrangment was adopted to achieve higher adhesion weights on relatively short runs.

The class hauled suburban trains to Riverside (11.1 miles), Downer's Grover (22.2 miles) and even some as far as Aurora (37.5 miles from Chicago). Riverside trains made 16 stops, Downer's Grove runs had 19 stops with 2-6 cars. The first of the two 1889 reports said that the engines were performing a regular service of 98 miles (158 km) and 107 stops per day with 3-4 cars on a creditable two tons of coal (40.8 lb/mile or 11.5 kg/km).

All had been retired by 1911.
