China's first unmanned, panda-shaped “Sky Train” rolled off the production line in Ziyang, Southwest China's Sichuan province on December 8, 2016. The renewable-energy unmanned suspension railway is battery-powered, with cute pandas painted through carriages. The unmanned train can carry a maximum of 144 passengers as it hangs and zips along the monorail track at speeds of up to 65 km/h. [Photo/Chinanews.com]
