Bengaluru's Yellow Line marks its first anniversary on August 11 with a full fleet of 15 six-car driverless trainsets — up from just three at launch — promising peak-hour headways of under five minutes for the corridor's 60,000+ daily commuters.
On August 11, 2025, Prime Minister Narendra Modi inaugurated the Yellow Line — Namma Metro's 19.15-kilometre corridor connecting RV Road in central Bengaluru to Bommasandra in the southern IT belt, via Electronic City. One year later, the line has received all 15 of its six-car driverless trainsets, with BMRCL targeting full fleet commissioning by the anniversary date.
From Three Trains to Fifteen in Twelve Months
The Yellow Line opened with just three operational trainsets, running at 25-minute headways — a frequency that frustrated commuters but reflected the reality of a staggered delivery programme. By November 2025, frequency improved to 15 minutes as more trains arrived from Titagarh Rail Systems Ltd (TRSL) in West Bengal, the Indian partner manufacturing the fleet in collaboration with China's CRRC Nanjing Puzhen.
The 13th trainset entered commercial service in June 2026, bringing peak-hour frequency down to roughly seven minutes. The 14th and 15th trainsets have since arrived at the Hebbagodi depot and are undergoing the mandatory testing cycle: assembly of the six-coach rake, static checks of electrical, signalling, braking and communication systems, approximately 750 kilometres of dynamic trials during non-revenue hours, and final safety clearance before entering passenger service.
Once all 15 trains are commissioned, BMRCL expects peak-hour headways of four to five minutes — a dramatic improvement from the 25 minutes commuters experienced at launch. Two of the 15 trains will be held as operational reserves.
60,000 Daily Riders Despite Early Constraints
The Yellow Line sustained approximately 60,000 daily riders even during its low-frequency months — a testament to the pent-up demand along the RV Road–Electronic City corridor, one of Bengaluru's most congested stretches. On its very first day of commercial service, the Yellow Line contributed to a system-wide record of 10.48 lakh rides (1,048,031 passengers), the first time Namma Metro had crossed the one-million mark in a single day.
The breakdown on that record day was striking: 4,51,816 passengers on the Purple Line, 2,91,677 on the Green Line, 52,215 on the brand-new Yellow Line, and 2,52,323 using interchange facilities at Nadaprabhu Kempegowda Station (Majestic) — Namma Metro's only tri-line interchange.
Made in India: 75 Percent and Rising
The Yellow Line fleet represents a milestone in India's metro manufacturing journey. The first 12 trainsets were assembled at CRRC's facility in Nanjing, China, with progressively increasing Indian-sourced components. The final three — the 13th, 14th, and 15th — were assembled entirely at Titagarh's facility near Kolkata, with at least 75 percent indigenous content by value.
Each six-car trainset runs on CBTC (Communication-Based Train Control) signalling, enabling fully driverless GoA4 operation — a first for any metro corridor in Bengaluru. The technology eliminates the need for a driver in the cab, with trains controlled by the Operations Control Centre at Hebbagodi. This is the same driverless standard planned for the upcoming Pink Line's underground section between Dairy Circle and Nagawara.
What Five-Minute Frequency Means for Commuters
The shift from seven-minute to four-to-five-minute peak headways is more significant than it sounds. At seven-minute intervals, a single missed train means a noticeable wait; at five minutes, the psychology changes — commuters begin treating the metro as a walk-up-and-ride service rather than one that requires planning around a timetable.
For the Electronic City tech corridor, where office start times cluster between 9:00 and 10:00 AM, higher frequency directly translates to lower platform crowding, shorter dwell times at stations, and a more reliable commute. BMRCL's projection of 30 lakh daily ridership by 2030 across the full network depends heavily on the Yellow Line carrying its share of that growth.
