Fully driverless metro Line 4 opened in São Paulo

ViaQuatro has started the full operation of São Paulo metro Line 4, Latin America’s first fully automated metro line (GoA 4) equipped with Siemens Mobility’s Communications-Based Train Control (CBTC) signalling.

“The full operation of Line 4-Amarela is a historic milestone in our efforts to expand and modernise the metro-rail system in São Paulo, and to offer a modern and increasingly reliable service to the passengers of ViaQuatro. We are pleased that Siemens Mobility will continue to contribute significantly to this end,” Francisco Pierrini, CEO of ViaQuatro and ViaMobilidade said.

Since its first stretch opened in 2010, it has been the first fully automated metro line in South America that can operate with GoA 4, the highest grade of automation that allows trains to be automatically controlled and operated. The digitalised and optimised system allows for a more efficient and centralised control of operations, while also increasing the safety, availability, and capacity across the entire network.

Originating at the main railway station Estação da Luz and recently extended to Vila Sônia, the line spreads over 15 km, using a fleet of 29 trains to connect 11 stations.

The Line 4, known as the Yellow Line, is operated by ViaQuatro, one of the companies of CCR Mobilidade, the division responsible for all urban mobility projects of the CCR Group in Brazil.

“São Paulo metro Line 4 has been the most innovative metro line in Latin America and our state-of-the-art digitalized technology can provide up to one million passengers per day with an enhanced passenger experience that features increased safety, reliability, and availability,” Andreas Facco Bonetti, CEO Siemens Mobility Brazil and Region Latin America said.

Since 2007, Siemens Mobility has been working with ViaQuatro to install digital signalling solutions, including CBTC-UTO (GoA4 driverless) Trainguard MT, telecommunication on board, train-to-track, interlocking-SICAS, VICOS and SCADA systems. The digitalised system will allow ViaQuatro to safely increase the number of vehicles on Line 4, and the greater frequency of train arrivals will give them the capacity to accommodate more passengers on the system. Additionally, the ability to continuously receive updates on system status will improve operational efficiency, resulting in fewer delays and more up-to-date travel information.
