Railway Tank Cars

Lake Oswego – October 05, 2026 -- The Greenbrier Companies (NYSE: GBX) has rejected antidumping and countervailing duty petitions filed by UTLX Manufacturing LLC, a Berkshire Hathaway subsidiary, over railway tank cars and parts, vowing to defend its record before the U.S. Department of Commerce and the U.S. International Trade Commission.

Greenbrier disputes claims it abandoned U.S. tank car production

Greenbrier operates a purpose-built tank car manufacturing facility in Marmaduke, Arkansas, where American employees currently build tank cars. The company noted that UTLX's own petition identifies Greenbrier as a U.S. producer and acknowledges its domestic tank car output in 2025.
