Built in 1988 for Union Pacific, this class F-100-38 centerbeam flatcar with Barber Roller Bearing trucks has a 263,000-pound gross weight and is used for carrying heavy finished wood loads, like plywood. With bulkheads on each end to prevent acceleration or deceleration load-shifting, the car design also features a centerbeam structure, which provides both lateral stability and support for shipment as well as simplifying loading and unloading cargo.
