Reduced Train Frequencies on North South Line (Feb 2018)

Reduced train frequencies on the North South Line (NSL) will take effect in the first week of February 2018 to facilitate additional engineering hours within the NSL tunnels. This will result in 10 to 15-minute train intervals along the NSL between Orchard and Marina South Pier, during the early morning and late night hours on Fridays and weekends.

In addition, there are also shorter operating hours along the East West Line (EWL) to facilitate additional engineering hours for re-signalling and maintenance work. This will involve early closures and late openings along the EWL. For more information, check out the dedicated article (Shortened Operating Hours on East West Line).

These closures allow more time for rail maintenance and renewal works to be carried out, as well as checks conducted on the new signalling system. In the wake of the Joo Koon train collision incident in November 2017, old and new signalling system-equipped sections of the EWL are physically separated until resignalling works are complete.
