Norfolk Southern keeps your business moving by shipping generators, transformers, farm and construction machinery, wind energy, and other similar commodities. Depending on the type of machinery you want to ship, certain dimensions might require special handling.

  • Is your shipment over 10’6 in width?
  • Is your shipment over 15’6 in loaded height?
  • Does the lading overhang the side sills or end of the railcar?
  • Does the length of the lading exceed 60 feet?
  • Is the load concentrated? (Is the load shorter than 18 feet?)
  • Will the car you use be loaded outside the plate as registered in UMLER?
Load extends beyond end sill of car
