Boxcar, 50 Foot, FMC, 5347

History: It was the mid 1970s, 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 1970s. The 50’ FMC cars also varied in door configuration and style to better suit each customer. These cars can still be seen today at work (2017) on many ralroads.

The main difference between the 5077 cu. ft cars built by FMC vs the 5277-5347 cu. ft cars built by the same manufacturers is the overall height of the car, the smaller 5077 cars were Plate B while the larger 5277-5347 cars were Plate C.

Railroad/Company: FMC Corporation is an American chemical manufacturing company headquartered in Philadelphia, Pennsylvania. The company was originally founded by chemist John Bean in 1883 as the Bean Spray Pump Company in Los Gatos, California, producing piston pumps for insecticides. In 1928, Bean Spray Pump purchased two companies: the Anderson-Barngrover Co. and Sprague-Sells Co. At this time the company changed its name to Food Machinery Corporation, and began using the initials FMC.

In 1941 the company FMC received a contract to design and build amphibious landing vehicles tracked vehicles for the United States War Department, and afterwards the company continued to diversify its products, including an extensive line of rail cars. The rail car production really kicked into high gear during the 1970s when FMC produced many models to take advantage of the Per Diem rules. Between 1965 and 1985 FMC was the owner of the Gunderson metal works in Springfield, Oregon, during that period it was known as the "Marine and Rail Equipment Division of FMC" (MRED), it was sold in 1985 to The Greenbrier Companies.
FMC employs 7,000 people worldwide, and had gross revenues of US$2.8 billion in 2017
