Susquehanna & New York 2-8-0 "Consolidation" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 111 (Locobase 13624)

Data from NdeM 1950 Locomotive Diagrams Standard Gauge supplied in December 2010 by Allen Stanley and from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 31, p 98. Works numbers were 24481 in July 1904 and 27270 in January 1906.

The 111 was originally intended for the West Virginia Northern, but was diverted to the S&NY, a coal road that was incorporated in Pennsylvania in 1903 as a consolidation of the Susquehanna & New York Railway and the Grays Run Railway Company. The railroad was owned by United States Leather and served as a bridge line for several larger roads including the Lehigh Valley, the New York Central, and the Reading.

The main line ran 43 miles from Towanda to Ralston, Penna. Add on the 12-mile branch composed of the former Grays Run Rwy and the total main-line mileage was 54.8 miles.

The S & NY sold both engines in 1919 to the Central Pennsylvania Lumber Company and both were sold to Rib Lake Lumber in Wisconsin in 1924 as their 67 and 69.

Class 114 (Locobase 13201)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. 234. Works number was 32123 in November 1907.

The 114 was a typically hefty coal mover of the late Saturated Age. Eventually, the locomotive wound up on the Central Pennsylvania Leather Company. It was scrapped in 1942.

Class 115 (Locobase 13203)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. 234. Works number was 39037 in January 1913.

The second Consolidation ordered by the S & NY retained the boiler design of the first (Locobase 13201) but substantially revised the firebox. The result was a wider, shallower furnace that increased grate area by nearly 50%. Revisions in the cylinder volume by reducing the stroke were offset by a 6" reduction in driver diameter, which combined to increase starting tractive effort.

Unlike the 114, which was sold before the S & NY was abandoned in 1942, the 115 remained in service. After the S & NY closed, the engine was sold to the US Navy's Naval Advance Base Depot in Davisville, RI. Apparently a wartime acquisition, the 3 was scrapped in August 1947.

Class 116 (Locobase 11019)

Data from Record of Recent Construction #98 (Baldwin Locomotive Works, 1920), p. 6 and DeGolyer, Vol 53, pp. 396+ . Works number was 44835 in January 1917.

This was the largest and latest of the four Consolidations that Baldwin built for this bridge line, which connected the Pennsylvania at March Hill Junction with the Lehigh Valley at Towanda. Steam admission came through 13" (330 mm) diameter piston valves and the firebox heating surface area included 29 sq ft (2.7 sq m) in four arch tubes.

In February 1943, 116 left the Northeast for the Deep South, where it served the Meridian & Bigbee River in Mississippi. In May 1955, the M & BR donated the 116 to Meridian. where it went on display at Highland Park.
