From 17 January to 19 April 2026, the two tunnels connecting Mountbatten, Dakota and Paya Lebar stations on the Circle Line (CCL) will be closed one at a time for essential tunnel strengthening works.

During this period, shuttle trains will operate on one platform, between Paya Lebar and Mountbatten stations at headways of 10 minutes using the tunnel that remains open.

To supplement CCL services and provide commuters with alternative travel options, new shuttle bus services will operate during weekday peak periods to bring commuters to unaffected parts of the train network.

These services will commence on 5 January, about two weeks before the start of the tunnel closure, so that commuters can familiarise themselves with a new travel route. These services will follow the same fare structures as the trains.
 

1. Shuttle bus service 38 between Paya Lebar and Stadium stations, operating between 6.30am to 9.30 am and 5pm to 8pm, at headways of 6 to 10 minutes;
    
2. One-way shuttle bus service 37A from Serangoon MRT station to Tai Seng, Macpherson and Paya Lebar stations in the morning from 7am to 9am at headways of about 3 to 5 minutes;
    
3. One-way shuttle bus service 37B from Tai Seng MRT station to Bishan MRT station from 5.30pm to 7.30pm at headways of about 3 to 5 minutes; and
    
4. One-way shuttle bus service 37C from Tai Seng MRT station to Serangoon MRT station from 5.30pm to 7.30pm at headways of about 3 to 5 minutes.
