The ATO will be installed above ETCS Level 2 on three passenger lines with a total length of 140 km.
SIEMENS Mobility has been awarded the contract to supply a complete digital signaling system providing automatic train operation (ATO) via ETCS Level 2 by Trivia Trens, the Comporte subsidiary that will operate the 11-Coral, 12-Sapphire and 13-Jade lines of the São Paulo passenger network in Brazil.
Under a 25-year concession contract signed with the São Paulo state government on May 21, Trivia Trens is currently recruiting and training staff. The handover will take place from the current operator of São Paulo Metropolitan Trains (CPTM) as part of a transitional phase lasting until July 2026, which can be extended until January 2027 if necessary.
The signaling contract covers 140 kilometers of line serving 46 stations, and represents the largest ETCS Level 2 deployment in Latin America, according to Siemens. The contract value was not disclosed.
The contract includes the design, supply, installation, commissioning and commissioning assistance of the new signaling system, and the modification of the onboard Trainguard ETCS units to a variety of rolling stock built by different manufacturers.
Fleet equipping will include:
- 107 EMU Trivia
- Six locomotives are owned by shipping company MRS Logística
- Three locomotives operated by Trivia and
- 17 maintenance vehicles.
Siemens will supply the advanced traffic management system (ATS), as well as the electronic interlock systems, radio mass center and complete track equipment, backed by a two-year warranty and supply of spare parts. The authority of the movement will be broadcast via Tetra Radio.
The ATO will enable operation at degree of automation 2 (GoA2), defining precise acceleration and braking patterns to optimize train progress. In addition to increasing capacity by up to 30%, Siemens says the ATO will significantly reduce energy consumption and peak power demand.
The streamlined structure of the new signaling system will significantly reduce maintenance requirements. With fewer trackside components and the potential to be upgraded in the future, “this solution represents a future investment to meet São Paulo’s growing mobility needs,” says Siemens.
“By implementing ATO for ETCS Level 2 in São Paulo’s busy urban network, we are setting new standards for automated urban rail transport in the region,” says Mark Ludwig, CEO of Rail Infrastructure at Siemens Mobility.
