Stadler modernizes the signaling technology in Atlanta

On 5 December 2024, the Metropolitan Atlanta Rapid Transit Authority (MARTA) has awarded Stadler the contract to equip its rail network with a new, modern train control system, within eight years of the start of the project. The replacement of the current system will improve train control, which will increase the ability of the trains to run on time and safely operate. For Stadler, the 500 million USD order represents an international breakthrough in the field of signaling. 

Stadler is equipping the trains with the NOVA Pro train control system. It is used in many cities and countries and meets international standards and requirements. Stadler's solution is characterized by a sleek, modular design that is compatible with any wireless communication network - including 5G and WiFi. The system can be flexibly adapted to various grades of automation (Grade of Automation: GoA). 

This will enable MARTA’s trains to run with the highest degree of safety and assist rail operators when operating the trains. A driver will still be on board operating the train and monitoring the journey and will intervene if necessary or in the event of an incident. This increases capacity, makes rail operations run on time and safely, resulting in direct customer benefits. The system is also more efficient, which saves costs. The addition of this system will make MARTA one of the most advanced transportation systems in the country. 

Stadler emphasizes partnering with Disadvantaged Business Enterprises (DBEs) in its signaling and rail vehicle projects to promote inclusive economic growth. The company supports the local community by leading education initiatives, including a youth apprenticeship program that engages many Title I schools. Stadler also encourages community involvement through employee volunteer days and sponsorship of youth sports teams in underserved areas, fostering opportunities for physical activity and development. Stadler is looking forward to bringing this community focus to Atlanta, as the company commits to building a local workforce and engaging with education, government and DBE partners in the area. 

Seamless integration of the new system 

For Stadler, the MARTA order is the largest order to date in the signaling sector. This order also marks the first time that a transportation company in the US has used a Stadler train control system with Stadler trains. The resulting synergies between the on-board and trackside signaling components will allow for a smooth introduction of the system and increase operational performance while minimizing downtime. 

The vehicles will be equipped with the necessary hardware at the Stadler plant in Salt Lake City, where the 56 new MARTA metro trains ordered in 2019 are being built. The trackside equipment will be installed, tested and commissioned directly on the MARTA network. As the on-board and trackside components come from the same supplier, the project can be completed seamlessly. During a transition phase, trains will be able to run with both the old and the new system. As soon as the trackside components have been installed across the board, the transition process to the new system will be smooth and without any interruption to operations.
