The test run was conducted on a 300 metre-long controlled track, separate from road traffic. Each 72-foot-long vehicle can carry up to 300 passengers, and up to four TEB cars can be linked together - although only one was used for its first public outing.

“The biggest advantage is that the bus will save lots of road space,” said Song Youzhou, the project’s chief engineer, in an interview with news agency Xinhua earlier this year.
