Santa Fe Refrigerator Despatch

The Santa Fe Refrigerator Despatch (reporting mark SFRD) was a railroad refrigerator car line established as a subsidiary of the Atchison, Topeka and Santa Fe Railway in 1884 to carry perishable commodities. Though the line started out with a mere 25 ventilated fruit cars and 8 ice-cooled refrigerator cars, by 1910 its roster had swollen to 6,055 total units (compared to the 8,100 units its largest competitor, the Pacific Fruit Express, operated).
