Yes. Federal Transit Administration and Federal Railroad Administration grants typically impose Buy America content requirements, meaning rolling stock procured with federal funds must meet domestic content and final assembly thresholds. Importers and project sponsors should verify compliance before sourcing foreign-built equipment for such contracts.

Rolling stock refers to wheeled vehicles that move on rails — including locomotives, freight cars, passenger cars, and specialized maintenance vehicles — as opposed to fixed infrastructure such as track, signals, or station structures. The distinction matters for both HTS classification and Buy America compliance determinations.
