Battery-powered trolleybuses conquered Mexico City
Mexico City has commissioned 63 battery-powered trolleybuses from Chinese manufacturer Yutong. 40 of the buses have already been delivered, the remaining 23 will follow in December.
These are O-buses that also have a battery to cover up to 100 kilometers on overhead lines. In the message, Yutong also speaks of a "dual drive" - but the vehicles no longer have a burner, it is rather the double drive from battery-electric and overhead line components.
