Earlier this year, civil engineers at the 19th China Beijing International High-Tech Expo unveiled plans for an innovative space-saving bus that rides above traffic rather than alongside it. It’s called the Transit Elevated Bus (TEB), and its unique design quickly gained a great deal of notoriety online. While some transit experts praised the bus’s road-straddling construction, others argued that it was merely a conceptual design that could never materialize into a real vehicle.

At the time, the TEB’s engineering time had nothing but a miniature scale model to demonstrate their invention. Now, just a few months later, a full-size TEB has taken its inaugural test drive in Qinhuangdao, Hebei province. The test drive was conducted in a controlled trial that didn’t exactly mimic normal driving conditions, but it did at least prove that the TEB could, in fact, be driven on a real roadway. The test drive consisted of a 300 meter run with one TEB bus carriage. Ultimately, the TEB’s designers plan to connect four of the carriages together so that a single bus could carry as many as 1,200 passengers. In addition to its one-of-a-kind design, the TEB is also unique in that it’s powered by a fully-electric drivetrain.

Even on a brief test run, watching the behemoth bus roll down the road while cars travel underneath it is an impressive sight. It’s hard to say if and when the bus will become commonplace on China’s roadways, but for now you can see the bus in action in this video of its first test run!
