Project Scope and Technology

The project will modernize lines 11-Coral, 12-Sapphire, and 13-Jade. The deployment involves a comprehensive digital signaling and control system to enhance capacity, safety, and operational efficiency. Siemens Mobility will design, supply, install, and commission a complete signaling system, including an Advanced Traffic Management System (ATS), modern interlocking systems, Radio Block Centre (RBC), and all related trackside equipment.

Equipment and Implementation

The project includes equipping over 130 vehicles with Siemens’ Trainguard ETCS on-board units. This includes 107 trains, six MRS locomotives, three TRIVIA locomotives, and 17 auxiliary vehicles. The agreement also includes a two-year warranty and the provision of spare parts.

Benefits and Operational Improvements

The implementation of ATO over ETCS Level 2 is designed to optimize headways, improve journey smoothness, and increase service frequency while adhering to stringent safety standards. Energy-efficient driving algorithms are expected to reduce energy consumption and peak power demand. The system’s architecture also enables future upgrades.

Executive Commentary

Marc Ludwig, CEO of Rail Infrastructure at Siemens Mobility, stated that the project demonstrates a commitment to bringing advanced rail technology to Latin America. He highlighted the potential for up to 30% increased network capacity. The project represents the largest ETCS Level 2 installation in South America.

Conclusion

Siemens Mobility and Trivia Trens are collaborating to establish a more reliable, sustainable, and digitally integrated rail network in São Paulo through the introduction of ATO over ETCS Level 2. This initiative aims to support growing passenger demand in the region.
