Guide To Know About Cross Island Line

A high-capacity Mass Rapid Transit (MRT) line called the Cross Island Line (CRL) currently built in Singapore. The CRL, the eighth MRT line, will travel from Changi to Jurong Industrial Estate in a broad east-west direction via Loyang, Pasir Ris, Hougang, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi, and the West Coast. 

The line will diverge at Pasir Ris and continue on to Punggol. The Cross Island Line, which will be at least 50 kilometres (31 mi) long and serve 30 over stations, is coloured lime on official maps.  It will be the fourth high-capacity MRT line and the sixth MRT line to be fully automated and driverless.

Line positioning

The alignment of the line’s Bukit Timah segment, which crosses the Central Catchment Nature Reserve (CCNR) and MacRitchie Reservoir, has been the subject of debate since it announced, leading the Nature Society Singapore to demand that the line realigned. A northern route would run close to the Thomson-East Coast Line and head west toward Mandai, Sungei Kadut, and Gali Batu before terminating at Choa Chu Kang, and a southern route would skirt the reserve along Lornie Road. Both proposed alternative alignments presented by the NSS on July 19, 2013, date their release. The ability to build the railway across the reserve without harming the environment was recognised by engineers, while one questioned the choice in  Cross Island Line.


Future high-capacity underground MRT line called the Cross Island Line (CRL) currently planned. It will be Singapore’s eighth MRT line to operate entirely automatically and without a driver when the first section of the line opens in 2030. A press release announcing the Land Transport Authority’s award of a Civil Contract for the Cross Island Line Phase 1 in March 2021 reported that the Cross Island Line passenger service start date had changed from 2029 to 2030.

The route will connect Changi’s Aviation Park to Jurong, travelling through neighbourhoods including Loyang, Pasir Ris, Tampines North, Hougang, Serangoon North, Sin Ming, Bukit Timah, and Clementi.

Upcoming stages

A future system showing a group of 11 unidentified stations western section of the CRL feature in a virtual display by the LTA in December 2021. The map also indicated that the western section connected to already-existing stations such King Albert Park, Clementi, and Jurong Pier. Gul Circle station is the line’s endpoint. Since then, both the map and the online display have been unavailable. The Straits Times predicted in February 2022, based on tender documents, that civil works on the CRL might be finished by the end of 2033, with operations starting in 2034 or later.

Services for Local & Express Trains

The Engineering Feasibility Study (Contract C1002 – Engineering Feasibility Study for the Proposed Cross Island Line) put out to bid by LTA in February 2014, and Arup Singapore Pte. Ltd. won the contract for S$7,988,000.00. The idea of running Local and Express services on the same line was taken into consideration as part of the engineering feasibility assessment.  However, Minister for Transport Khaw Boon Wan provided a written response to Mr Ong Teng Koon’s parliamentary question on November 19, 2018, asking whether there were plans to include express trains in new MRT lines.
