Union Pacific has formally unveiled its Arrowedge® employee-designed aerodynamic technology for fuel and locomotive emissions reductions for use on double-stack intermodal freight trains. UP expects to introduce the technology on intermodal service between Joliet, Ill., and Long Beach, Calif., this month.
UP says that Arrowedge®, three years in development, "is the latest innovation in Union Pacific's ongoing commitment to design, build and implement fuel-saving technologies."
"The Arrowedge® represents Union Pacific's focus on pioneering technology for operational and environmentally sustainable gains that ultimately result in enhanced customer service and community stewardship," said Mike Iden, Union Pacific general director-car and locomotive engineering. "We are excited to see the results of this innovation in action and how it can springboard further research and development."
Positioned on top of the first freight container, the 48-foot Arrowedge® has a tapered body that allows air to more easily flow around the train's top frontmost containers. This reduces aerodynamic drag for more efficient transport of customers' goods. In addition, drag reductions decrease the amount of locomotive power required to propel the train, UP says,
UP says it holds two U.S. patents for the Arrowedge®, with additional U.S. and Canadian patents pending.
