US freight cars can no longer use parts from rival countries or state-owned companies

New rules ban US freight cars from using parts or technology from specific rival countries or state-owned enterprises. This means freight car manufacturers must now track the origin of every component and ensure compliance.

For decades, freight car manufacturers could source parts globally based on cost and availability. These new rules force a shift in supply chains, prioritizing national security concerns over pure economic efficiency. It means companies must now build entirely new sourcing relationships and potentially pay more for components.
