Siemens Mobility has announced it will modernize three lines of São Paulo’s transport network, marking the largest deployment of Automatic Train Operation (ATO) over European Train Control System (ETCS) technology in Latin America.
The project includes designing, supplying, installing, commissioning, and assisting with the operation of a new signaling system across three lines. Siemens Mobility will equip trains from various manufacturers with Trainguard ETCS onboard units. The scope also covers an Advanced Traffic Management System (ATS), modern interlocking systems, a Radio Block Centre (RBC), and complete trackside equipment. The contract provides for a two-year warranty period and spare parts.
According to Siemens Mobility, "ATO over ETCS represents the cutting edge of rail technology, combining two advanced systems to maximize operational efficiency and safety." The company explained that ETCS Level 2 offers continuous digital supervision and control of train movements via TETRA radio communications. Meanwhile, the ATO system automates driving functions to Grade of Automation (GoA) Level 2.
"This technological integration enables precise acceleration and braking patterns, exact stopping at platforms, and optimized headways between trains," Siemens stated.
The company said that implementing this advanced technology is expected to transform commuter rail operations in São Paulo by increasing service frequency and reliability. Optimized driving algorithms are designed to reduce energy consumption and peak power demand. Additionally, the streamlined system architecture is intended to minimize maintenance needs.
With fewer trackside components required and options for future upgrades, Siemens Mobility described the solution as a future-proof investment for São Paulo’s growing transportation demands.
