O 3 Rail C&O Locomotive 7505 Unpowered (ATO30138103)

Chesapeake & Ohio 7505 is a 3-rail O-gauge unpowered locomotive that captures the late-1940s transition from steam to diesel power. This model recreates the look of GM E-series locomotives in authentic C&O livery, with railroad-specific detailing and precise painting and lettering designed to pair with other 3-rail equipment on an O gauge layout.

Built with a die-cast metal chassis, fuel tank and trucks, and featuring all-metal grab irons, it delivers a sturdy, highly realistic presence on the layout. The unpowered model shares the line’s high level of detailing—from accurate decoration to close-coupling between units—while matching the era’s proportions at about 12.5 inches long. Steam generator detail appears on the appropriate A or B unit according to railroad specifications, and layout fit is straightforward on 3-rail tracks, with minimum curves of O-36 for A-units and O-45 for B-units.
