Have you ever seen a train that is hung in the air? Such a train has appeared in Chengdu already.

The train is powered by lithium batteries (锂电池) instead of electricity. It is not only energy-saving but also environmentally friendly compared to other trains. Each coach will be able to carry up to 120 passengers.

The train has done its test without any problem a short time ago. But further tests will be done to check the train’s ability to turn and climb up the tracks before it can be open to the public.

Chengdu is the first city in our country to build such a train system, and Shanghai will also open one this year. Shanghai started plans for its “Skytrain” in 2015.

The “Skytrain” in Shanghai will run above the ground at a height of around six meters. The columns which will support the railway will be just 80 cm wide. The columns are so narrow that they could even be built in the green belt in the middle of the road. The train Shanghai plans to use will have just four coaches (车厢), and each coach will hold 70 passengers. The train will run at around 30 kilometers per hour. It will be a little slower than the city’s subway trains, which run between 30 and 40 kilometers per hour.

“Skytrain” would cost about 120 to 150 million yuan to build. Developers said the train system will carry around 15,000 passengers every hour. The space-saving train system would run silently through the city.
