Built by the American Refrigerator Transit Company this refrigerator car (reefer) was used to carry fresh fruits, vegetables, and other perishables, protecting from extreme temperatures.  Bunkers at the ends of the car held portable heaters in the winter and 10,000 lbs. of crushed ice in the summer.  It was constructed with 4 inches of horse-hair insulation on the sides and end walls and 4½ inches in the roof and floor.  The #52461 was donated in 1958 by the American Refrigerator Transit Company.
