Mumbai Metro Line-3 commuters can collect stamps across 10 stations as the Aqua Line Passport and Stamp Trail launches Friday, at a special anniversary price of Rs 250.
The collectible will be available from 11 am onwards and can be purchased through digital payment only. It will be distributed on a first-come, first-served basis, with limited quantities available.
The initiative invites commuters to explore Mumbai's Aqua Line, officially known as Metro Line-3, while collecting stamps at designated stations along the route.
The Passport and Stamp Trail will be available at 10 stations: Cuffe Parade, Churchgate, Hutatma Chowk, CSMT Metro, Worli, Siddhivinayak, Dharavi, Bandra-Kurla Complex, CSMIA-T2 and Marol Naka.
The initiative aims to offer commuters and metro enthusiasts a collectible experience linked to their journeys on the Aqua Line, which connects key locations across Mumbai.
Interested commuters can visit the designated stations to purchase the limited-edition collectible from Friday, October 16, onwards, subject to availability.
The time capsule will remain sealed for 10 years and is scheduled to be opened on October 8, 2036, marking a decade of full-route operations.
According to MMRC, the capsule contains photographs, records, milestones and memorabilia documenting the development and operation of Mumbai's first underground metro. The initiative aims to preserve the Aqua Line's journey and offer future generations a glimpse into its early years.
MMRC described the initiative as a first-of-its-kind in India's metro sector.
The Mumbai Metro Rail Corporation (MMRC) introduced the Aqua Line Passport and Stamp Trail as part of its anniversary celebrations on October 9, encouraging commuters and travel enthusiasts to explore the metro corridor and collect specially designed commemorative stamps.
MMRC also felicitated its most-travelled commuters during the anniversary celebrations, recognising their continued use of the Aqua Line.
The celebrations marked one year of full-route operations on Mumbai's underground metro corridor, which connects key locations across the city.
Meanwhile, the MMRC has recorded more than 7.2 crore passenger journeys on the Aqua Line as the entire corridor completed one year of full-route operations.
The underground metro corridor from Aarey JVLR to Cuffe Parade has recorded 7,20,88,738 cumulative passenger journeys, marking a major milestone for Mumbai's first underground metro line, an official statement said.
The Aqua Line has continued to attract commuters since the entire corridor became operational, it said.
In September 2026, the line recorded an average daily ridership of 2,24,602 on weekdays and 1,31,138 on weekends, according to MMRC.
