New York, Ontario, & Western / New York, Ontario & Western 2-8-0 "Consolidation" Type Locomotives

Class P (Locobase 3944)

Typical anthracite-burning camelback delivered to the NYO&W at the turn of the 20th century as described in . Railroad Gazette (23 March 1900). This locomotive was intended for pusher service on coal trains, according to George W. West, Superintendent of Motive Power, who designed it.

Cooke delivered the class over 4 years, the last three arriving in March 1904. All of them remained in service until the late 1940s.

See William D. Edson's roster in Railroad History Bulletin 175 for builder's numbers. Note that the first 14 had Cooke serials (2509, 2566-2568, 2646-2651, 2710-2713) and the last 6 were blended into the total Alco count (26242-26244, 29286-29288).

Class P - superheated (Locobase 9005)

Data from NYO&W 1 - 1943 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

Locobase 3944 describes the original configuration of this camelback Consolidation design.

Class S (Locobase 3150)

Data from McShane (1899), supplemented by D&HCo 1901 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection.

A typical anthracite-road camelback freight engine pair of the turn of the century; although this design - Dickson works #911-912 -- is relatively small. They were delivered as compounds, but didn't stay with the NY, O & W for long.

The D & H diagram book reveals that these engines were sold to the D & H in 1896 and renumbered 93-94 (and later 700-701) as their class E. They were disposed of by 1927.

Class W/W-2 (Locobase 9009)

Data from NYO&W 1 - 1943 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive collection. See William D. Edson's roster in Railroad History Bulletin 175 for builder's numbers. It shows that production of this class began in July 1910 with 48137-48142 and 48355-48363. Six months later, the class resumed with works #49410-49415 and ended in February 1911 with 49704-49709.

After building up a big stud of camelback Consolidations, the NYO & W chose a conventional-firebox design for its last procurement of new 2-8-0s. Like most of the rest, these came from Alco's Cooke works in Paterson, New Jersey. They were powerful and, when superheated, put out relatively dry steam.
