Lebanon Springs 4-4-0 "American" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 11696)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 16, p. 59. See also Data from Dimensions and Classifications of Locomotives of the NYC&HR et al, September 1905, p. 325. Works numbers were 10841 in April 1890 and 10849 in May.

The LS had a relatively long independent history, which began when it was organized on 25 March 1852 to run from Chatham, NY to the Vermont border.. Several reorganizations followed as did periods when the line was run under lease to such other railroads as the Central Vermont. In 1888, the LSRR and the Bennington & Rutland Railroad were to be merged as the New York, Rutland & Montreal. In September 1899, the LS was reorganized as the Chatham & Lebanon Valley and this pair was renumbered 6 and 9, respectively.

The Rutland's acquisition of the C&LV resulted in a further renumbering. The New York Central owned the 174-175 (renumbered 797-798 and designated C-29) from 1905 to 1912 (when the 798 was wrecked) and 1913, when the 797 was restored to the Rutland., where it was retired in November 1915.
