The last set of Mohawk 4-8-2s acquired by the New York Central were the 25 members of class L4b, delivered from Lima Locomotive Works in 1943-44. Like the L3 class, the L4s were equally at home in heavy freight or fast passenger service. Many representatives of both classes were later fitted with the "elephant ear" smoke deflectors visible on No. 3137, which I photographed at Mackinaw City, Michigan in August 1954. The L4s carried a boiler pressure of 250 pounds per square inch, and had 26x30-inch cylinders. With 72-inch drivers, they exerted 59,900 pounds of tractive effort and had a grate area of 75.3 square feet. Their tender held 43 tons of coal and 15,500 gallons of water, and the total weight of both locomotive and tender was 766,700 pounds. Class L4b was the first class on the NYC system to feature the multiple-bearing crosshead instead of the "alligator" type still used on the J3 and L3 classes. (The multiple-bearing crosshead also appeared on the Niagara 4-8-4s and the P&LE A2 2-8-4s.) By the time I was photographing steam, even these modern Mohawks had been displaced from most of the NYC's main lines and relegated to more lightly traveled lines like the Mackinaw City branch.
