Gondola, Woodchip

History: Although they are one of the lightest loads carried by rail, they require one of the biggest cars! Wood chips are big business for today's saw mills and lumber operations. Once burned as scrap or fuel-on-site, these by-products of the lumber industry are purchased by paper companies and used to make paper.

Specially designed for the pulp and paper industry, these cars can hold up to 6,800 cubic feet of pulpwood chips. Open-top gondolas without doors, end doors or bottom gates are designed for top loading. Unloading can be performed by top, end or bottom, depending on car design.

Railroad/Company: Gunderson traces its roots to 1919 when Chet Gunderson opened Wire Wheel Sales and Service Company of Portland, Oregon. His brother, Al Gunderson joined in 1923 and shortly thereafter Gunderson Brothers was born. They became a leading steel fabricator and manufactured thousands of vital ship components during World War II. They also built lifeboats and life rafts: 3,600 by 1945.

Peace-time barges began in 1949 and the first order of railcar underframes came in 1958. In 1985, The Greenbrier Companies acquired the former Gunderson Brothers operations from FMC Corporation and restored the Gunderson name to the Portland waterfront. Since that time, Gunderson has established itself as a leader in engineering and manufacturing railcars and marine barges.

As of 2018, Greenbrier's Gunderson division is one of the largest producers of intermodal railcars.
