SINGAPORE: Train services on the Circle Line (CCL) will end earlier on some days between Jun 15 and Jul 30 to prepare for the opening of the complete CCL loop next year, with services ending at 11pm from Sundays to Wednesdays. The adjustments are necessary for renewing the Integrated Supervisory Control System (ISCS) and ensuring compatibility with the new CCL6 extension, which will add three new stations and complete the line. Commuters are advised to plan their journeys accordingly and rely on alternative routes during this period.
