On the hilly roads in the center of Chongqing city in China, traffic congestion composed of buses, taxis, and private cars is particularly bad, and the exhaust fumes from this traffic is continuing to worsen atmospheric pollution. As a public-transport measure to address this pollution problem, a straddle-type monorail has been introduced. As the first urban monorail introduced in China, the Chongqing monorail was opened to the public on June 18th, 2005. As a major partner in the Chongqing monorail project, Hitachi manufactured and installed two prototype trains (with a total of eight cars) and their mass-production bogies, electrical equipment, and points and crossing equipment. After that, 19 mass-production monorail trains (with a total of 76 cars) were manufactured and implemented by Changchun Railway Vehicles Co., Ltd in technical cooperation with Hitachi. The main features of this monorail train are as follows: large urban monorail cars, completely painted exteriors of aluminum car bodies to protect against acid rain, a VVVF (variable voltage, variable frequency) traction inverter, and fiber-reinforced-plastic seats and stanchion poles used inside cars.
