This small 4-wheel Plymouth gas-mechanical was used by the City of Detroit to switch coal cars at the Misterky Power Plant. Today the locomotive switches cars in Greenfield Village. It has a Climax six-cylinder engine with a 4-speed manual transmission and direct chain drive. It's seen here at the Greenfield Village roundhouse, which incorporates parts of the original 1881 Detroit, Toledo & Milwaukee roundhouse that stood at Marshall, Michigan.
