Stadler modernizes the signaling technology in Atlanta with CBTC

The Metropolitan Atlanta Rapid Transit Authority (MARTA) has awarded Stadler a contract to modernize its train control systems throughout the entire rail system. Under the terms of this major contract, Stadler will replace the current system
with a new generation train control system within eight years of the start of the project.

Stadler is equipping the trains with the NOVA Pro train control system. 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 CBTC – state-of-the-art train control system
CBTC stands for “Communication-Based Train Control”. CBTC is an advanced train control system that uses wireless communication to precisely track trains at all times. Thanks to the real-time information on train positioning, trains can be operated more precisely, safely and efficiently.

Stadler's CBTC technology is recognized worldwide as a proven and widely used solution for metro systems. 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). As a result, it offers the flexibility needed to meet the growing demands of public transit providers.

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.
