Boxcar, 50 Foot, Gunderson 5200

History: Built in the late sixties and early seventies, the Gunderson 5200 is a classic-looking boxcar with modern appeal and can still be seen around today (albeit usually not in the best of shape!). Constructed near the end of the internal post, double sheathed box car era, the straight sill and centered YSD 8ft doors lends itself to clean modern symmetry on a car with vintage aesthetics. These cars road on ASF 70 Ton Ride Control or Barber 70 Ton S-2 trucks. They were used by the BN, SP and SP&S.

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.
