Shanghai Keolis, operator of the line, is a joint venture between the Shanghai Shentong Metro Group and France-based Keolis.

With a lightweight design and an intelligent energy management system, the driverless trains will consume less energy compared with regular trains.

In addition, the use of rubber tires allow the trains to accelerate faster with less noise.
