St. Louis Refrigerator Car Co. #4466, an ice-cooled refrigerator car, passes through Limon, Colorado on November 9, 1951.
The St. Louis Refrigerator Car Company (SLRX) was a private refrigerator car line established on February 3, 1878, Anheuser-Busch's first subsidiary. The company formed to facilitate large-scale distribution of the company's products via the U.S. rail network. The SLRX not only built its own reefers, but maintained and operated them as well.
In 1919 the firm was acquired by Manufacturers Railway Company (MRS), another A-B transportation subsidiary. The St. Louis Refrigerator Car Company currently owns the "Dome Railway Service" in Wood River, Illinois.
