en.Wedoany.com Reported - Alstom has signed a contract with Companhia Paulista de Trens Metropolitanos (CPTM) to supply and install a new railway signaling system for the Mauá Norte yard on Line 10-Turquoise in São Paulo.

Located between Mauá and Capuava stations, the yard is being built by CPTM and includes six new tracks for shunting, marshaling, and non-operational train storage. Alstom will equip it with a complete signaling system to enhance operational safety, efficiency, and train management capabilities.

The contract covers the supply, installation, testing, and commissioning of electronic interlocking, switch control equipment, trackside signals, and train occupancy detection devices. The system is designed to Safety Integrity Level 4 (SIL 4), the highest internationally recognized railway safety standard.

In addition to signaling equipment, Alstom will provide closed-circuit television, telecommunications infrastructure, access control systems, and dedicated railway radio communications. The new system enables controllers to monitor track occupancy in real time, helping optimize train allocation and scheduling decisions while reducing conflicts with mainline operations. The project is expected to reduce delays, improve service reliability, and create safer working conditions by reducing reliance on manual operations.

Suely Sola, Managing Director of Signaling and Infrastructure at Alstom Brazil and Latin America, stated that a highly reliable and available signaling system is crucial for optimizing yard operations management, enabling better train set allocation, increasing operational capacity, and reducing service delays and failures. The signaling solution, developed by Alstom, has been deployed in several projects across Latin America. The company noted that the entire system will be designed and delivered using Brazilian labor to support local skills development and domestic industry.

The project also includes integrating the new yard with the existing signaling systems at Capuava and Mauá stations, enabling continuous communication between adjacent railway infrastructure. Operations will be managed through a local control center and two remote monitoring stations connected to the Line 10-Turquoise operations control center, allowing real-time monitoring and centralized traffic management. Alstom expects to complete the project within 18 months, followed by six months of operational support, with the contract also including a two-year warranty period after commissioning.
