Hartford & Connecticut Western 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class P-2 - 1882 (Locobase 6644)

Data from 1915 CNE Classification of Locomotives book supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 3096 in September 1882, 3299 in July 1883, and 3346 in September.

All three of the locomotives were reboilered and it isn't clear to which one of the three upgrades the data from the Classification book refer. Beaujon's H&CW roster compilation shows that H&CW successor Central New England rebuilt 16 in July 1900 with a new boiler from Baldwin. 17 received an extended front end from the CNE in July 1890 and a new boiler in April 1901. Finally, 18 got its new boiler in July 1901 along with an extended saddle.

The CNE condemned 35 (ex-16) on 20 November 1919. 36 followed in October 1925, and 37 finished the class in July 1926.
