Central New England & Western 4-4-0 "American" Locomotives

Class Details by Steve Llanso of Sweat House Media

Class F / P-3 (Locobase 6643)

Data from 1915 CNE locomotive diagram book supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works number was 11208

The CNE&W soon was reorganized as the Philadelphia Reading & New England (1892) and later as the Central New England (1899). In its final incarnation as class P-3 (joined by two others apparently produced by other builders), 32 persisted until April 1915.
