Zhangjiang Tram is one of the only two tram networks operating in Shanghai today, the other being Songjiang Tram. It utilises a system manufactured by the French Translohr company. Shanghai originally had a steel wheeled electric tramway network in its urban center. Routes expanded gradually and reached largest extent in 1925 with 328 tramcars; this tram system shut down in 1975. Tram service returned to Shanghai with the opening of a rubber tired Translohr line in the suburban Zhangjiang Hi-Tech Park in 2010. It is the second rubber-tired tram system in both China and Asia, the first being TEDA tram in Tianjin.
