Kolkata Metro’s Blue Line services will be suspended on parts of the route for five Sundays between 15 November and 13 December 2026, with the interruptions scheduled from 9 am to 6 pm for maintenance work. The changes will affect passengers travelling beyond Mahanayak Uttam Kumar towards Shahid Khudiram, and later towards Maidan.
According to an official statement from Kolkata Metro Railway, services between Shahid Khudiram and Mahanayak Uttam Kumar will remain suspended on 15, 22 and 29 November and 6 December. On 13 December, the affected section will extend from Shahid Khudiram to Maidan. The service restrictions will apply during the same 9 am to 6 pm window on all five Sundays.
During the first four maintenance periods, trains will continue to operate between Dakshineswar and Mahanayak Uttam Kumar. Passengers travelling beyond Mahanayak Uttam Kumar towards Shahid Khudiram will therefore need to make alternative transport arrangements during the suspension hours.
The disruption has been announced to allow maintenance work on parts of the metro railway corridor. The source report, citing the Metro Railway’s official communication, did not specify the individual maintenance activities or the assets involved. However, the planned Sunday schedule indicates that the railway is limiting the work to defined daytime windows while retaining operations on the remaining section of the Blue Line.
For commuters, the effect will be concentrated on the southern section of the corridor and will vary on the final Sunday. On the first four Sundays, passengers will be able to use the Blue Line between Dakshineswar and Mahanayak Uttam Kumar, but will not be able to continue by metro to Shahid Khudiram during the maintenance period. On 13 December, services will be suspended between Shahid Khudiram and Maidan, according to the published details.
Metro Railway expects regular Blue Line operations across the affected sections to resume after 6 pm on each of the five Sundays once the scheduled maintenance period ends. The last trains from Shahid Khudiram and Dakshineswar are expected to run according to their regular timetables.
The railway has advised passengers to check service updates before travelling, particularly the maintenance timings and the section affected on the day of their journey. The planned interruptions will begin on 15 November and continue on the specified Sundays through 13 December.
