Container Car, Single Well, Gunderson Husky Stack 40 Rebuilt

History: Single unit wells, especially the Gunderson car , are referred to as Stand-Alone or "Huskies." They can carry heavier loads, like Tanktainers, since the trucks do not have to support two wells, as in an articulated well car. Since the 1990s, when international trade has increased, there is a higher demand for 40' well cars. Often, 53' and 48' well cars had been drafted into service to carry 40' containers which was a waste of space. So 8 feet was cut from the middle of the 48' cars, making the 40' rebuilt well car. TTX has produced many of these 'choipped' well cars.

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.
