BYD's Skyrail monorail system was fixed to the track for testing Friday in Guangan in Southwest China's Sichuan Province, making it the first of its kind in the province. The rail section is 8.5 kilometers long. Wang Chuanfu, chairman of leading Chinese new-energy car maker BYD, said in January the company believes Skyrail, which is relatively cheap and easy to build, will be worth 10 trillion yuan ($1.54 trillion) in the Chinese market in 20 years.
