Better thinking for inside your boxcars.

Why product protection in boxcars is crucial.

Front view of a train engine

Properly secured unitized goods requires special attention.  During transit, items are subject to load shifts, sudden impact, and careless handling.  More than risking the quality of the goods, you risk the following as well: 

  • Customer dissatisfaction and loss of repeat business
  • Rejected loads
  • Increased costs due to replaced, salvaged, or disposed product
  • Possible penalties and fines
  • Employee injury
  • Lost sales

Boxcars have a unique set of challenges for transportation specialists. Let our Down River Load Securement professionals set you up with the products, experience, and knowledge to design a load-securement system to meet your specific guidelines, needs and products.

No one offers a more complete line.
