German industry giant Siemens has equipped São Paulo's Metro Line 4 with its radio-based train control system (Communications-Based Train Control, CBTC).
ViaQuatro has thus successfully launched the full operation of the entire line. Since the opening of the first section in 2010, it has become the first fully automated metro line in South America to operate with GoA 4, meaning the train is automatically controlled without any staff on board.
This is the highest level of automation that enables automatic control and operation of the trains. The digitized and optimized system enables more efficient, centralized control . . .
