Heaviest and most powerful 4-6-2 type locomotives of the Central Railroad of New Jersey were the five locomotives of class G-4s erected in 1930 by Baldwin Locomotive Works, the railroad's newest road engines. (The "s" in the classification indicated a superheated locomotive and was later dropped.) Weighing 333,830 pounds, they developed 52,180 pounds of tractive force. Their 74-inch drivers departed from the 80-inch standard set by the railroad's earlier classes of Pacifics, although their cylinder dimensions were the same at 26x28 inches. Their boiler pressure was 240 p.s.i.; they had 3591 square feet of evaporative heating surface, 1000 square feet of superheating surface, and a grate area exceeding 84 square feet. In 1945 the Jersey Central reclassified these engines to P-52. No. 814, last member of the group, posed for the Baldwin builder's photo; all were retired by 1955.
