Union Pacific Debuts Aerodynamic Feature for Stack Trains

Union Pacific Railroad has developed new technology to increase the aerodynamic efficiency of double-stack intermodal trains.

Union Pacific Debuts Aerodynamic Feature for Stack Trains

Dubbed Arrowedge, the 48-foot unit is positioned on top of the first freight container. It features a tapered body which allows air to more easily flow around the train's top front-most containers, reducing aerodynamic drag. The result, said UP, is more efficient transport of goods, as well as a decrease in the amount of locomotive power required to propel the train. UP holds two U.S. patents for the Arrowedge, with additional U.S. and Canadian patents pending. The railroad said it expects to introduce the technology into double-stack train service between Joliet, Ill. and Long Beach, Calif. this month.
