Railway Solutions by Union Junction Foundry

Precision-Engineered Railway Components for Superior Performance and Reliability

The Union Junction Foundry, located in Gauteng, South Africa, is one of the largest foundries in the Southern Hemisphere and a leading supplier of single-piece, thin-walled locomotive and passenger car bogie frames, freight car components, and high-integrity steel railway wheels.

The foundry holds American Association of Railroads (AAR) approval for the manufacture of locomotive frames, freight car side frames, bolsters, and cast steel railway wheels, ensuring compliance with international quality and safety standards.

A recently commissioned state-of-the-art production line—comprising a closed-loop moulding facility, a 40-tonne-per-hour sand reclamation plant, and an in-line after-cast processing system—has significantly enhanced manufacturing capacity within the existing Union Junction foundry buildings. This advanced system is capable of producing at least 3,150 sets of freight wagon bogie components per year (11,200 tonnes).
