Dura-Max™

To meet the need for reliable railcars to haul aggregate, crushed rock and gravel, Greenbrier has designed the Dura-Max, a 2,400 cubic feet open top hopper. With input from aggregate shippers, the Dura-Max has a 286,000 lbs gross rail limit and transverse doors operated by a single cylinder per set of doors for individual door control. Our steel body design provides superior strength and durability throughout the life of the car.
