The Marx 994 was Marx’s largest tin-bodied locomotive. It dates to 1952. It wasn’t made for very long, but thanks to its size, collectors still like the Marx 994 locomotive.
Marx released the 994 in 1950 to compete with Unique Art, a rival maker of tin toys who had entered the market in 1949. Unique’s trains were priced like Marx’s and ran on the same O gauge track but were slightly larger, which made them appear to be a better value. Marx countered by introducing its own line of trains in a similar size.
