Lima Locomotive Works supplied the Peoria & Eastern's three representatives of class L1d, 4-8-2s Nos. 46-48, in 1918. These workhorses weighed 348,000 pounds and developed 54,080 pounds of tractive effort. By 1940 a booster tractive effort of 11,000 pounds was listed for this class. These engines had 69-inch drivers and 22x28-inch cylinders, and sustained a boiler pressure of 200 pounds per square inch. Although some 0-8-0 switchers were newer, these Mohawks appear to have been the newest over-the-road motive power assigned to the Peoria & Eastern before World War II.
