MTH - Premier Freight Cars - 50 ft. Ps-1 Double Door Box Car - O Scale 3 Rail 

Pullman had been making freight cars for more than half a century when it hit a home run with the PS-1 box car. Introduced in 1947, it set the standard for post-WWII American freight cars. What made the PS-1 a landmark was its welded construction - an area in which Pullman-Standard led the industry. In addition to lighter weight, welding offered superior strength and better resistance to weather and corrosion than contemporary rived cars.
