FreightCar America intends to close its Shoals manufacturing facility in Alabama and move all its operations to Mexico, the railcar manufacturer said Thursday. The Chicago-based company already operates in Castaños, Mexico, via a 50-50 venture with Fabricaciones y Servicios de México, S.A. de C.V., also known as Fasemex. FreightCar America is seeking to acquire the remaining 50% and consolidate all of its production there by January.
