| Early Closure of Circle Line (Jun–Jul 2025) | |
| Affected Dates | Sundays – Wednesdays from 15 June 2025 to 30 July 2025 |
| Period of closure | On affected days, train services will end at around 11:00 pm |
| Affected sector | Entire Circle Line (Dhoby Ghaut/Marina Bay – HarbourFront) |
| Reason | Renewal of Circle Line Integrated Supervisory Control System (ISCS) |
| Alternative Transport | MRT Bridging Buses not offered Passengers advised to consider other rail lines and alternative transport modes |
According to SMRT and LTA, early closures are needed to facilitate a series of works on the existing CCL to renew its ISCS, to ensure system compatibility with the new Circle Line Stage 6.
The ISCS monitors and manages the systems on the CCL, including power supply, communications and station facilities. It also supports communications between stations, control centres and trains.
The service adjustments are required to provide longer blocks of engineering hours necessary for testing and commissioning of the new servers and equipment to be carried out safely and rigorously.
