Sky train is set : China's first sky train off for a first run

China's first sky trains are out of the assembly line and into the tracks in the city of Nanjing, making China the third country to master the sky train technology, after Germany and Japan.
Sky train is a light, medium-speed rail system that operates above the ground. It mainly supplements public transportation in big metropolises.
The Nanjing Puzhen Company Limited, affiliated to China's largest state-owned rolling stock manufacturer CRRC Corporation Limited (China Railway Rolling Stock Corporation), took only four months to design and complete the elevated railway trains, said CRRC.

The two compartments can hold more than 200 passengers, and when compared with subways and trams, sky trains have lower costs, better climbing and turning ability, and higher wind resistance.
Professor Yue Zhaohong at the Beijing Jiaotong University said the construction period of sky trains is also much shorter than that of subways, lasting only three to five months for completing dozens of kilometers.
The overhauled railway is driven by batteries which can run for four hours at a time, and the batteries can be changed when the train stops at a station, with the entire process lasting only two minutes.
Experts say the sky train is more environmentally friendly. They will be a good choice in third and fourth tiered cities and at scenic spots. The sky trains are also set to debut in many of China’s scenic spots next year.
