Bengaluru’s highly anticipated yellow Namma metro line, which was supposed to facilitate overload on busy sections, such as a silk plate and a bommasandra, is finally open. However, relief may be short -term for commuting. The trains will initially take place at 25 -minute intervals, because only three train sets are prepared for service.
Reason for a 25 -minute delay?
This limited start can wear barely 25,000-30,000 passengers per day, deep below the capacity of 2-3 lakh £The 400-Crore-Per-kilometer project was planned. According to the Times of India, the slowdown of the last minute outage is not, but the result of years of delay caused by pandemies, bureaucrats, diplomatic obstacles and disturbance of the supply chain.
From contract to complications
Problems began in December 2019, when BMRCL granted the Chinese company CRRC Nanjing Puzhen a contract for 216 trainers. Twelve trains were to be built in China, and the rest was made in India as part of the “Make in India” plan. CRRC even bought 50 acres in Andhra Pradesh for the factory.
By 2021 the plan stopped. CRRC failed to obtain the necessary permits to start production in India. In December that year, BMRCL issued an end notice and turned the matter to the court. In April 2022, the High Court in Karnataka allowed the contractual agreement to continue, with more time granted CRRC.
The Chinese company cooperated with Titagarh Rail Systems LTD in May 2022 to produce 34 trains in India. Geopolitical tension, however, after Galwan conflict brought new problems – CRRC engineers could not get visas enter India for more than a year. Without them, the key assembly and test work were stuck.
Slow arrival of trains
The visa was eventually released in December 2023, which allowed the CRRC teams to work on the spot. The first prototype from China arrived in February 2024 for testing. Indian trains began to be introduced in May 2024. Since August 2025, BMRCL has only three train sets. Soon the fourth is expected, which could reduce the waiting time to 20 minutes. The entire fleet of 15 trains, which is required for a 5 -minute tip frequency, is reportedly expected until March 2026.
Why can’t trains borrow
The yellow line uses CBTC (train control), a modern signaling system that allows closer train intervals and better energy efficiency. However, this system is incompatible with trains on purple and green line that uses different technologies. The retrofitting would be expensive and time consuming.
In addition, 57 trains on the existing lines are hardly sufficient for their own plans and other undulating supplies were also delayed.
