The Cross Island Line is a future high-capacity underground MRT line currently under planning. Targeted for completion in 2030, it will be the eighth MRT line in Singapore, employing a fully automated and driverless mode of operation.

The line will run from Changi to Jurong, passing through residential estates such as Loyang, Pasir Ris, Hougang, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi and West Coast and terminating in the Jurong Industrial Estate. A branch line will connect Pasir Ris and Punggol.

First announced in January 2013, the line will connect with all radial lines, with 13 interchange stations along its 30-odd station alignment significantly enhancing the connectivity of the rail network. In addition, it will provide an important rail link between the Central, North-East and West areas.

The Western Depot will occupy the site of Raffles Country Club while the Eastern Depot has yet to be announced. While still under planning, the line is intended for 8-car trains, making them the longest MRT trains in Singapore. The possibility of operating Local and Express services on the same line are also being considered.

Timeline & History

  • 17 Jan 2013: Cross Island Line announced as part of the Land Transport Master Plan 2013
  • Aug 2014 – End 2016: Environmental Impact Assessment

First announced in the Land Transport Master Plan 2013, the 50-kilometre Cross Island Line traverses the island from East to West, relieving congestion on the existing East West Line and Downtown Line and opens up new transport corridors for central Singapore regions. The line will serve Changi, Loyang, Pasir Ris, Hougang, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi, West Coast and the Jurong Industrial Estate, with a branch line extending into Punggol.

The Land Transport Authority (LTA) is studying the use of both normal and express trains on the Cross Island Line, and if so, the stations which Express trains should serve. Such a plan would likely see Express trains calling at major interchange stations only.

While still under planning, the Eastern end of the line will likely join up with Changi Airport Terminal 5, interchanging with the Thomson-East Coast Line extension.

Alignment comparison

The alignment of the Cross Island Line through the Central Catchment Nature Reserve was the subject of much public debate, with nature groups and members of the public voicing their concerns about such an arrangement. A direct alignment would see the line tunneling underneath the Nature Reserve, while a skirting alignment would see he line diverted around the reserve via Lornie and Upper Thomson.

An Environmental Impact Assessment (EIA) was carried out from August 2014 to End 2016 to study both possible alignments. Soil Investigation works began in March 2017. The final alignment will be decided will only be decided at a later date, after soil investigation works are completed.
