This dataset includes public (common carrier) tariff rates for fertilizer shipments on 26 major rail corridors. Fertilizer commodities include potash, urea, urea ammonium nitrate (UAN), monoammonium phosphate (MAP), and diammonium phosphate (DAP). The dataset provides tariff rates and fuel surcharges for two car ownership types (privately-owned and railroad-owned railcars) and three train types (manifest, unit, and shuttle).
