Alstom has announced the commencement of passenger services on the 7.5 km elevated priority section of Bengaluru Metro's Pink Line Reach 6, equipped with its communications-based train control (CBTC) signalling technology. The section connects key residential, educational and healthcare hubs across South Bengaluru, strengthening the city's urban transport network.The priority section operates under Grade of Automation 2 (GoA2), enabling automatic train operation (ATO) from the first day of revenue service, a first for an Indian metro project. Under this system, train acceleration and braking are automated, while the driver remains responsible for essential operational functions.The project also includes the fully commissioned Kothanur depot, equipped with automatic train protection (ATP), and an integrated test track featuring ATO capabilities. These systems are designed to support safe, reliable and high-frequency metro operations.The six stations covered under the elevated section are Swagath Road, Jayadeva Hospital, JP Nagar 4th Phase, Indian Institute of Management, Hulimavu and Gottigere. Jayadeva Hospital station provides an interchange with the Yellow Line, improving connectivity across South Bengaluru.Alstom's CBTC signalling system enables continuous communication between trains and trackside equipment, supporting precise train positioning and operations for six equipped trainsets. Train movements are monitored through the Urbalis Vision platform at the Operations Control Centre in Baiyappanahalli.The company has also deployed its HealthHub predictive maintenance solution, which provides real-time monitoring of signalling assets to minimise downtime and optimise lifecycle maintenance costs.Olivier Loison, Managing Director, Alstom India, said, We are proud to see our CBTC technology power Bengaluru Metro's Pink Line. This milestone reflects our team's commitment to deliver world-class, reliable signalling solutions to help the city transition to a sustainable and connected future.The Pink Line project marks Alstom's third contract with Bengaluru Metro Rail Corporation Limited (BMRCL). The company previously supplied signalling solutions for Phase I's Purple and Green Lines between 2009 and 2017 and is involved in traction and power supply electrification works for Phase II.With more than 30 years of experience in CBTC technology, Alstom's signalling systems have been selected for 190 metro lines globally, including 18 lines equipped or under development across India.The project further strengthens Alstom's role in advancing automated metro operations and supporting the expansion of sustainable urban mobility infrastructure in India.
