Bengaluru’s long wait for the Pink Line has crossed an important operational milestone. The first driverless metro train built for the corridor has reached Kothanur depot, marking a shift from construction and planning to testing and system integration. The six-coach train has been manufactured by Bharat Earth Movers Limited and will now undergo a series of rigorous safety and performance checks before it is cleared for trial runs.
This arrival is significant as it marks Bengaluru Metro’s first step towards fully automated train operations. While driverless metros are common in many global cities, this is a new phase for the Namma Metro and will require extensive validation before public use.
Why this arrival matters for Bengaluru
The arrival of the train is not symbolic. This signals the beginning of a longer test cycle that will check braking systems, signaling compatibility, communications-based train control and emergency response mechanisms. Each system will be tested repeatedly under controlled conditions at the Kothanoor depot.
The Pink Line is being developed as part of the city’s larger metro expansion plan, with automation expected to improve service reliability, safety and operational efficiency. Officials consider driverless technology essential to manage higher passenger numbers in the future without increasing operational stress.
Pink Line route and planned rollout
The Pink Line extends for 21.3 kilometres, connecting Kalena Agrahara in south Bengaluru to Nagavara in the north. The corridor will have 13 stations and is expected to significantly reduce travel time in some of the busiest areas of the city once fully operational.
Testing will begin on the 7.5 km elevated section between Kalena Agrahara and Tavarekere, which has been given priority as it is structurally ready. This section will allow engineers to test the system in a relatively controlled environment before expanding testing into underground sections.
As per current targets, commercial operations are planned on this section with five driverless trains by June 2026. The entire Pink Line is expected to open to the public by the end of 2026, consisting of a total fleet of 16 trains.
How did the train reach Kothanur depot?
Metro train transportation through Bengaluru is a logistical exercise that cannot be done during the day. Each coach was moved from BEML complex in New Thippasandra to Kothanur depot during late night, covering a distance of about 20 kilometres.
City regulations restrict the movement of large trailers during daytime to avoid traffic disruption. As a result, officials carefully coordinated the transportation, ensuring that the coaches reached the depot safely without affecting the regular traffic flow.
Features of driverless trains
The new trains are built using stainless steel, selected for durability and low long-term maintenance requirements. These are designed to be energy efficient, with systems that optimize power consumption during acceleration and braking.
Passenger convenience has also been given priority. The coaches feature wide gangways, thoughtfully designed seating layouts and USB charging ports to optimize mobility during peak hours. Safety systems are layered and integrated with automated controls, and each train must undergo several rounds of testing before certification.
Impact on Bengaluru’s daily commute
Once operational, the Pink Line is expected to reduce pressure on several congested road corridors and provide predictable travel times for commuters who currently rely on buses or private vehicles. Areas along the route are expected to have better connectivity and reduced dependence on surface traffic.
However, experienced travelers know that testing, certification, and system integration can take time. Although deadlines are in place, officials have indicated that safety and reliability will be prioritized over speed.
a clear step forward
The Pink Line has faced delays and challenges, causing frustration among passengers. However, the arrival of the first driverless train represents solid progress. With the physical rolling stock now in the depot, the project has moved beyond drawings and tunneling to a significant operational phase.
For Bengaluru, this is not the end of the journey, but it is a clear sign that the Pink Line is finally gaining momentum.
