In 1950, Marx introduced the largest locomotive it ever made, the Marx 21 Santa Fe diesel. Marx made both powered and unpowered versions, and they were dressed up in the same warbonnet scheme as Lionel’s iconic F3 diesels, but unlike Lionel’s effort, they were nearly 1:48 scale (proper for O gauge) and made of metal.
Marx only made them for two years.
