New subway train exhibited in Berlin

A new type of subway train featuring new material and a smart system exhibited at InnoTrans in Berlin on Tuesday. The train was developed by CSR Sifang in China. As the body of train is made of carbon fiber, the train weighs less than normal trains and is more energy efficient. The train uses a self-driving system with a top speed of up to 140 km/h (87 mph).
