Technology

The train is designed for use on systems in the 20,000 to 60,000 passengers/hour range. The design of the train bodies is by Porsche Design. Modules in the system include various vehicle ends, doors, gangways, roof-mounted air-conditioning, and interiors. Many combinations of motor cars and trailers are possible, with individual vehicle lengths from 17 to 25 metres and widths from 2.6 to 3.2 metres. Stainless steel or aluminium construction is available, in three cross-sections: straight sidewalls, sidewalls sloping at 3 degrees, and contoured.
