Big Four class Y, later class B-3
New York Central class C-76
In 1893, Schenectady built ten 4-4-0 locomotives for the Big Four which were to be used on the Columbus Division. Designed by E.P. Lord, they had a Belpaire firebox, inside Stephenson valve gear, outside cylinders and 69-inch drivers. Already in the year of their delivery, Railroad Gazette reported that they were faster with trains of ten to twelve cars than the 4-6-0 class N previously used on the same lines. They became class Y and later class B-3.
They carried non-consecutive numbers between 100 and 205, while their works numbers were 3952 to 3961. For a short time, No. 134 had a trailing axle with no side play to reduce the axle load. In 1905, they became New York Central class C-76. In 1907, the NYC assigned them to their subsidiary Erie & Western. In 1919, four were superheated and had their slide valves replaced by piston valves. All were retired between 1922 and 1925 and subsequently scrapped.
