Daily commuters on Bengaluru's Namma Metro are expected to get relief from overcrowded trains soon. The Bangalore Metro Rail Corporation Limited (BMRCL) plans to introduce three new six-coach trainsets on the Green Line by August 2026. This move comes more than a year after the prototype train arrived in the city and is expected to improve train frequency and reduce crowding on one of the metro's busiest routes.
Bengaluru Metro New Trainsets
The three trainsets are part of a new fleet being supplied by China Railway Rolling Stock Corporation (CRRC) in partnership with Titagarh Rail Systems Ltd. (TRSL). The prototype train, which reached Bengaluru in January 2025 after several delays, was originally planned for the Purple Line. However, BMRCL has now decided to use it on the Green Line.
According to a senior BMRCL official, all three Distance-To-Go (DTG)-enabled trainsets have been received. Testing has taken longer because the Green Line is already operational, so trial runs could only take place after passenger services ended each night. Despite these limitations, most of the testing work has been completed.
Bengaluru Trainsets to Complete Performance Trials
Before entering passenger service, the trains must complete several performance trials, obtain 37 statutory safety clearances, and receive approval for rolling stock. BMRCL has already completed oscillation trials, received approval from the Railway Board, and finished signalling integration tests. The trains will now undergo a final inspection by the Commissioner of Metro Railway Safety (CMRS). If approval is granted, they are expected to begin service by August.
BMRCL will deploy all 23 CRRC-Titagarh trainsets on the Green Line. While three have already been delivered, the remaining 20 are being built at Titagarh Rail Systems' factory in Uttarpara, West Bengal.
Once the new trains start operating, the existing Green Line trainsets will be shifted to the Purple Line, which has the highest passenger traffic. This redistribution will improve train availability and reduce overcrowding on both lines. The new trains also feature Distance-To-Go technology and are similar to the modern trains used on the Yellow Line.
The project faced major delays after CRRC failed to set up a manufacturing unit in India as required under a ₹1,578-crore contract awarded in 2019. The issue was resolved after CRRC partnered with Titagarh Rail Systems, allowing production to continue in India and helping the long-pending project move forward.
