This Union Refrigerator Transit Lines URTX # 37144 car was built in 1948.by General American Transportation Co. The 'X" in URTX indicates the car was privately owned while the Milwaukee Road herald show it was leased to that railroad. Number 37144 is 40' long & weights 61,500 lbs. The car is a steel bodied reefer with iced bunkers at each end. These ice bunkers hold 10,400 lbs. of chunk ice or 11,500 lbs. of crushed ice. Ice stations were located every 100-150 miles along the railroads main line to replace the melted ice. In the winter, charcoal heaters could be placed in the bunkers to keep the cargo from freezing. Fans are located in the floor at each end to circulate air and keep an even temperature throughout the car. Typical cargo would be fresh fruit, vegetables or eggs. This reefer car was donated in 1975 by the General American Transportation Corporation.
