The design of the Metrocars was partly derived from that of the German Stadtbahnwagen B, although the Metrocars were built by the now-defunct Metro-Cammell in Birmingham (now part of Alstom) and were not fitted with the lights and indicators that would have allowed them to run on city streets.
The track was also used to test cars for the Hong Kong MTR, also built by Metro-Cammell.
