The FM H-24-66 Trainmaster is a classic and unique American diesel locomotive. Lionel Trains made many versions in the 1950s and has some modernized versions as well. The FM Trainmaster is a 2400 Horsepower diesel with FM's unique and controversial opposed-piston diesel engine. The big diesels were used on only a few railroads in the 50s and 60s. If we get an FM H-24-66, it needs to be either in the SP "Black Widow" paint, the SP "Bloody Nose" (red/grey) paint, or in PRR livery. The PRR engine could have some new freight cars and a caboose for the Horseshoe Curve Route. The SP engines could have freight cars and a caboose or a consist of commuter cars. The engines would be great on both Donner Pass and the Peninsula Corridor Routes.
