Circle Line MRT services to end early from Sundays to Wednesdays between June 15 and July 30

Train services on the Circle Line (CCL) will end earlier, at 11pm, from Sundays to Wednesdays between June 15 and July 30.
This is to facilitate system renewal works ahead of the opening of Stage 6 of the line in the first half of 2026, said the Land Transport Authority (LTA) and rail operator SMRT on May 22.
CCL6 - which comprises three new underground stations, Keppel, Cantonment and Prince Edward Road - will close the loop between HarbourFront and Marina Bay stations.
LTA and SMRT noted that train services on Thursdays, Fridays and Saturdays will remain unchanged.
The renewal works are required as the current integrated supervisory control system - which monitors and manages power supply, communications and station facilities on the CCL - has been in use since the opening of the line in 2009, they said.
The system needs to be refreshed to ensure it is compatible with the new stretch of stations on CCL6.
Adjustments to service are, therefore, needed to provide longer engineering hours to allow safe and rigorous testing and commissioning of the new servers and equipment.
The authorities advised passengers to plan their journeys and rely on other MRT lines and bus services to reach their destinations.
Posters will be displayed at all CCL MRT stations and other rail interchanges that connect with the CCL to alert the public to these changes. Station staff will also be deployed at affected stations to help passengers.
SMRT and LTA said that further service adjustments will be needed, tentatively from September to December, in order to complete systems integration testing across the entire CCL and ensure that the CCL6 stretch is well integrated with the rest of the line.
More details about these future adjustments will be provided later.
