You're probably right, although NYO&W may have used double-cabbers on its West Shore trackage rights.
But as far as I know, no camelback locomotive ever operated on the West Shore, except for this motion picture.

Excerpt from New York Central Headlight, June 1954
The Central's passenger station at West Point, N.Y., was filled with arc lights and costumed actors and smelled of grease paint when Columbia Pictures went "on location" there last month.
Hollywood stars Tyrone Power, Maureen O'Hara and Donald Crisp came to the famed United States Military Academy to make "The Long Gray Line," a Technicolor CinemaScope production to be released to theaters this fall.
New York Central came to the aid of the Hollywood artists when the shooting script called for a sequence to show the Army "shavetails" boarding trains at West Point in 1916, bound for overseas assignments with the AEF. The West Shore Division supplied a baggage car and three coaches as "props" for the scene. Since the highly dieselized Central no longer has any steam engines in the area, the Jersey Central Lines supplied a steamer of the type used in the World War I era to complete the train.
