December 6, 2021 12:36 pm



This article explores the significant modernization project undertaken by the Lisbon Metro, focusing on the strategic partnership between Stadler and Siemens Mobility. The €114.5 million contract encompasses a multifaceted approach to enhance the Lisbon Metro’s operational efficiency, safety, and passenger experience. This modernization initiative involves the delivery of new rolling stock by Stadler, coupled with the implementation of a cutting-edge Communications-Based Train Control (CBTC) system by Siemens Mobility. This project serves as a compelling case study illustrating the growing trend of integrating advanced technologies in urban rail systems to optimize performance and sustainability. The analysis will delve into the technical specifications of the new trains, the functionalities of the CBTC system, and the broader implications of this modernization for the Lisbon Metro’s overall infrastructure and operational capabilities. Finally, the long-term effects and broader implications of this successful public-private partnership on the future of metro systems globally will be assessed.

Stadler’s Contribution: New Rolling Stock for Lisbon

Stadler, a leading Swiss rolling stock manufacturer, is responsible for delivering 14 new three-car metro trains as part of the Lisbon Metro modernization project. These 49.6m-long, 2.78m-wide vehicles will be constructed using a modular design methodology, facilitating ease of maintenance and repair. The modular design is crucial for efficient lifecycle management, allowing for simplified component replacement and reducing downtime. The use of stainless steel in the car body ensures a robust yet lightweight structure, optimizing both durability and energy efficiency. The trains will be equipped with the Communications-Based Train Control (CBTC) GoA2 system, offering the potential for future upgrades and enhanced operational flexibility. This commitment to a modular and sustainable design underlines Stadler’s dedication to providing long-term value and minimizing lifecycle costs for the Lisbon Metro.

Siemens Mobility’s Role: Implementing CBTC Technology

Siemens Mobility’s contribution centers on the implementation of its Trainguard MT CBTC (Communications-Based Train Control) system. This advanced signalling technology will be deployed across the Blue, Yellow, and Green lines of the Lisbon Metro, impacting approximately 70 existing trains and the 14 new Stadler trains. CBTC systems enhance operational efficiency by enabling precise train control and spacing, leading to increased capacity and service frequency. The system’s GoA2 (Grade of Automation 2) functionality provides real-time data on train speed and position, allowing for safer and more efficient train operation. This real-time monitoring improves safety by preventing collisions and optimizing headway, allowing for a greater number of trains operating on a given track section. The implementation of this system signifies a significant technological upgrade for the Lisbon Metro, improving reliability, availability, and overall safety standards.

Project Scope and Timeline

The €114.5 million contract encompasses more than just the supply of new trains and CBTC technology. It also includes comprehensive technical training for Lisbon Metro personnel on operation and maintenance of the new equipment. This training is vital to ensure the long-term success of the project, empowering local staff to effectively manage and maintain the upgraded systems. Furthermore, the contract covers the supply of spare parts and consumables for preventive maintenance over a five-year period. This proactive approach to maintenance minimizes unexpected downtime and maximizes the lifespan of the upgraded infrastructure. The project’s timeline extends to approximately 77 months, with interim acceptance planned for 2027. This timeframe reflects the complexity of integrating new rolling stock and advanced signalling technology into an existing metro network.

Conclusion: A Paradigm Shift in Urban Rail Modernization

The Lisbon Metro modernization project, spearheaded by the Stadler and Siemens Mobility consortium, exemplifies a paradigm shift in urban rail infrastructure development. The strategic integration of advanced technologies such as CBTC and the implementation of sustainable rolling stock design principles are not merely upgrades, but rather a commitment to enhancing the long-term efficiency, safety, and sustainability of the metro system. The project’s success hinges not only on the technical advancements but also on effective knowledge transfer and capacity building through comprehensive training programs for Lisbon Metro personnel. The emphasis on modular design, proactive maintenance planning, and long-term support underscores a holistic approach to infrastructure management. The modernization will not only improve the daily commutes of Lisbon’s citizens but will also serve as a model for other cities looking to upgrade their aging metro systems and integrate sustainable urban mobility solutions. The project’s success reinforces the importance of collaborative public-private partnerships in delivering large-scale infrastructure projects, effectively combining private sector innovation with the public sector’s operational expertise and long-term vision for sustainable urban transport. The benefits extend beyond Lisbon, providing valuable insights into best practices for modernizing urban rail systems globally and setting a benchmark for future projects in terms of technological advancement, operational efficiency, and sustainability.
