posted on 26th Mar 2026 10:22
Siemens Mobility, in consortium with Sonda México SA de CV, has been awarded a landmark contract to deliver the ETCS Level 1 for the Mexico City - Querétaro - Irapuato corridor. Spanning more than 300 km and serving eleven passenger stations, the project is part of Mexico’s federal initiative to modernize passenger rail infrastructure.
Siemens Mobility’s scope also includes the delivery of its TPS.plan software, a powerful train planning system that optimizes timetables and rail operations, alongside ETCS Level 1 wayside signaling, an Operational Control Center and backup, as well as Supervisory Control and Data Acquisition (SCADA) systems. Consortium partner Sonda will provide telecommunications, CCTV, and civil works.
“This contract marks a significant milestone for Siemens Mobility, as it represents our first ETCS project in Mexico and the debut of our TPS.plan train planning software in Latin America,” says Marc Ludwig, CEO Rail Infrastructure at Siemens Mobility.
Additionally, Siemens Mobility will, for the first time in Latin America, implement TPS.plan, a cutting-edge software solution developed by its subsidiary HaCon. This application enables precise timetable and track path optimization by leveraging microscopic infrastructure modeling to create conflict-free schedules. TPS.plan also simplifies coordination by granting stakeholders full access to the most up-to-date planning status, ensuring efficient and seamless rail operations.
The project marks a key milestone in Mexico's rail modernization, significantly enhancing mobility for workers, students, and commuters in the Bajío region. By connecting the capital with the states of Hidalgo, Querétaro, and Guanajuato, the line strengthens regional connectivity to Mexico City, boosts economic competitiveness, and aligns with federal goals for sustainable passenger rail.
