Updated quarterly, the dataset includes public (common carrier) tariff rates for 15 major rail corridors for soybean meal shipments. Of this total, 11 routes are for manifest movements (i.e., shipments of less than 100 cars), and 4 routes are for unit train shipments (i.e., shipments of 100 cars or more). Additionally, the dataset provides rates and fuel surcharges for two car ownership types (privately-owned and railroad-owned railcars) and train type (unit train and manifest service).
