Chesapeake & Ohio Locomotive 7024 Powered O Gauge (ATO30138079)

Chesapeake & Ohio 7024 Powered O Gauge 3-Rail Locomotive is a postwar diesel-era model designed to bring authentic late-1940s motive power to model railroad layouts. Recreating GM’s 1947 era E and F-series locomotives, this powered three-rail model features steam generator detail on the A or B unit where appropriate, a highly detailed body with railroad-specific markings, and directional golden-white LED lighting for realistic operation. Twin flywheel motors provide smooth, consistent pulling power for long freight runs or passenger trains.

Built for durability and realism, the model features a die-cast chassis, fuel tank and trucks, all-metal grab irons, and close-coupling between units. It weighs about 5 pounds per unit and measures roughly 12.5 inches in length. The lineup includes powered and unpowered options, with minimum curves of O-36 on the A unit and O-45 on the B unit for 3-rail operation (2-rail minimum radius is 36 inches). Accurate painting and lettering, paired with period-appropriate color schemes, make this a convincing centerpiece for 1947-era railroading on modern layouts.
