As a significant milestone to modernize its aging train control and rail safety systems, Metropolitan Atlanta Rapid Transit Authority (MARTA) signed a contract with Alstom Signaling, Inc. to deliver the train control system used by MARTA personnel to direct train movement, control traction power, and monitor transit stations and other auxiliary functions. The new system will significantly improve rail service for MARTA customers while also improving operational safety, efficiency, stability, overall productivity, and capabilities for future system expansion.
As part of this contract, Transdyn was selected to design, build and deliver the SCADA portion of the train control system which will be installed at both the primary and backup control centers and at three rail maintenance yards. Seamlessly integrated, the train control and SCADA systems will function as the nerve center for MARTA’s rail operations to safely direct train movements and provide operations personnel with timely system and field equipment information.
Transdyn’s DYNAC® Enterprise Server (ES) software will serve as the modern SCADA platform and will enhance management of MARTA rail operations. From the central train control system Human Machine Interface (HMI), operators will utilize information gathered by DYNAC® to monitor and control traction power substations, lighting, escalators, fare gates and radio systems at passenger stations and other facilities throughout the MARTA rail system. Transdyn will also deliver approximately 100 remote terminal unit (RTU) based programmable logic controllers (PLCs) equipped with DYNAC® HMI for local control capabilities at various MARTA locations.
Roughly 50 replacement train controllers being supplied by Alstom Signaling, Inc. will utilize DYNAC® HMI for local operation and system management.
Not only does the state-of-the-art SCADA technology address current rail management and operational needs, but it also establishes a solid foundation for future growth. The modular design of DYNAC® provides the Authority with a scalable system that will accommodate future technologies and transit line extensions without risk of system obsolescence.
For over thirty years, MARTA has served as the ninth largest transit system in the United States and provided combined bus and rail service to the City of Atlanta and DeKalb and Fulton counties. MARTA provides approximately 500,000 passenger boardings each weekday and helps to remove more than 100,000 cars off Metro Atlanta roads each day.
