On July 12, 2026, Singapore opened the final 4.3-kilometre section of the Circle Line metro, closing the loop between Harbour Front and Marina Bay. This addition completes a continuous circular route after three decades of phased construction.
New Stations and Heritage Integration
The extension introduced three underground stations: Keppel, Cantonment, and Prince Edward Road. Cantonment station is uniquely integrated with the historic Tanjong Pagar railway station, a national monument. During construction, parts of the old railway platforms were removed but canopy structures were reinstated post-completion to preserve the site’s heritage. All new stations feature full accessibility, including lifts, escalators, and tactile guidance. Energy-efficient technologies such
as smart lighting, motion-sensor controls, and hybrid cooling systems have been implemented. Facilities like bicycle parking and covered pathways encourage access by walking and cycling.
Circle Line Network Details
The Circle Line now spans 39 kilometres, comprising a 35.5-kilometre main ring and a branch to Dhoby Ghaut. The network includes 33 stations, of which 12 serve as interchanges with other lines. This connectivity enables passengers to bypass traditionally congested transfer points such as City Hall and Raffles Place stations.
Train Fleet Expansion and Depot Capacity
Service enhancements include the introduction of 23 Class C851E Alstom Metropolis trainsets delivered from Spain, which began operation in April 2026. These trains supplement existing
C830 and C830C fleets, raising the total to 87 trains on the line. Kim Chuan Depot, responsible for servicing the fleet, has nearly doubled its capacity from 70 to 133 trains. The depot also houses a fleet of 550 buses to optimize land utilization.
Construction Challenges in Dense Urban Areas
Constructing this final stage posed engineering challenges due to the dense urban environment and proximity to port facilities. Tunneling beneath the operational Keppel Viaduct and the removal of undocumented underground coastal structures required careful management to maintain operational safety and structural integrity.
Enhanced Wayfinding for Circular Service
The Land Transport Authority developed improved wayfinding systems tailored for the Circle Line’s clockwise
and anticlockwise services. Enhancements include upgraded static signage, passenger information displays, and clear announcements that indicate upcoming interchange stations. A pilot implementation of these improvements began at Promenade, Esplanade, Buona Vista, and Paya Lebar stations in late May 2026 to prepare passengers ahead of the line’s completion.
Passenger Benefits from Circular Connectivity
Passengers now have access to a continuous circular metro route around Singapore, improving travel options across the city. Connections to all other lines on the Circle Line facilitate interchange without needing to pass through busy central stations, reducing congestion. The integration of accessibility features and sustainable facilities supports multimodal travel and urban inclusivity.
