OPERATING concessionaire ViaQuatro has begun full operation of metro Line 4 - Yellow in São Paulo, with communications-based train control (CBTC) supplied by Siemens Mobility now enabling driverless operation under the highest grade of automation, GoA4.
Siemens says that Line 4 is the first fully automated metro line in Latin America.
Line 4 runs from São Paulo’s main railway station at Estação da Luz and has been recently extended to Vila Sônia and its full length of 15km, serving a total of 11 stations.
It is operated with a fleet of 29 trains and has a capacity of up to one million passengers a day.
In addition to its Trainguard MT CBTC-UTO technology for GoA4 driverless operation, Siemens Mobility has supplied its Sicas interlocking system, train to track communications and a Scada system.
Siemens says that its CBTC technology will enable ViaQuatro to operate more frequent services on Line 4, increasing capacity with the line expected to serve up to 1 million passengers per day.
The ability to continuously receive updates on system status will improve operational efficiency, resulting in fewer delays and more up-to-date service information for passengers.
“Full operation of Line 4 is a historic milestone in our efforts to extend and modernise the metro system in São Paulo, and to offer a modern and increasingly reliable service to our passengers,” says ViaQuatro CEO, Mr Francisco Pierrini.
