The centerbeam flatcar has a full-height longitudinal center partition running the length of the car, with load secured to both sides of the beam using straps and load bars. This bilateral loading configuration doubles the load density compared to a standard flatcar for certain commodities. Centerbeams are primarily used in lumber and building products service in Western North America. The center spine provides structural rigidity and a tying surface for bundled lumber, wallboard, and particleboard.
Full-length center partition with flat decks on each side; primary equipment for dimensional lumber and sheet goods.
Hinged end sections that fold down to simplify loading of extra-long lumber with a forklift or crane.
Centerbeam flatcars are the preferred equipment for Western lumber mills shipping dimensional lumber, panel products, and building materials east to construction markets, where unit trains maximize mill-to-distribution throughput.
