Athearn 3901 - Minnesota Dakota & Western

It was the mid 1970’s, and the incentive per diem box car boom was just beginning. New, brightly painted box cars seemed to appear overnight. Many were lettered for various short lines. FMC (Food Machinery Corporation) was a significant builder of many of these cars. The 50’ outside post, non-terminating end box car, became the foundation for new per diem cars built in the 1970’s. The 50’ FMC cars also varied in door configuration and style to better suit each customer. These models can still be seen today in the modern railroading scene.
