The Cross Island Line is tentatively coloured turquoise in this MRT system map.

The Cross Island MRT Line (CRL) will be the eighth Mass Rapid Transit (MRT) line in Singapore.^[2] It is currently under planning and evaluation.^[3]

The line will begin from Changi, passing through Loyang, Pasir Ris, Hougang, Ang Mo Kio, Bukit Timah, Clementi, West Coast before terminating at Jurong Industrial Estate.

History

The line was first announced by the Land Transport Authority on 17 January 2013.

Overview

Targeted to be completed by 2030, it will offer East-West commuters an alternative to the existing East West Line. It will also connect to all the other major lines to serve as a key transfer line, complementing the role currently fulfilled by the orbital Circle Line.^[4]

The eastern leg of the line will include a segment that branches out from Pasir Ris and extends into Punggol. ^[3]

Based on the Ministry of National Development Land Use Plan,^[5] this line is expected to interchange with the East West Line at Clementi and Pasir Ris, Downtown Line at King Albert Park MRT Station on Stage 2 (DTL2), Thomson-East Coast Line at Bright Hill, North South Line at Ang Mo Kio, and the North East Line at Hougang and Punggol.

Alignment controversy

Since its announcement on 17 January 2013, there has been a controversy over the alignment of the line's Bukit Timah stretch as it appears to cut through part of the Central Catchment Nature Reserve (CCNR) and MacRitchie Reservoir, hence prompting the Nature Society Singapore to call for a change in the alignment of the line, although the Land Transport Authority insisted that the alignment of the line was not finalised as soil investigations and feasibility studies have yet to be conducted until an Environmental Impact Assessment (EIA) was commissioned to study the impact the line would have on the natural habitats of the reserve. Various stakeholders, including nature and environmental groups, will be engaged and consulted to ensure that their views and concerns are accommodated as part of the Environmental Impact Assessment study. On 19 July 2013, the NSS has put forward, in a position paper, two proposed alternative alignments for this stretch of the Cross Island Line. The LTA claims that none of the trees or plants (vegetation) above the ground will be affected.^[6]

The proposed alignments include a northern route that would run close to the Thomson Line, heading west towards Mandai, Sungei Kadut and Gali Batu before terminating at Choa Chu Kang, which will be an interchange to the North South Line, Bukit Panjang LRT and the upcoming Jurong Region Line. The other route will run along Lornie Road and was cited to "add 1.7 kilometres to 2 kilometres to the Cross Island Line, and an estimated four minutes' additional travel time. It would present an opportunity to serve residents near Adam Road and visitors to the MacRitchie Reservoir Park", running almost parallel to the stretch of the Circle Line from Marymount to Botanic Gardens. However, engineers noted that "it may still be possible to construct the tunnels along the original proposed route without disturbing the nature reserve, but this must be examined in detail" and that a "straight rail line is better and cheaper from the engineering and operations point of view".^[7]

On February 24 2014, the LTA called for a tender to assess the environmental impact of the line, targeted for completion by 2016. The study will help to facilitate in the subsequent civil works for the line.^[8]

On 3 July 2014, the LTA appointed Environmental Resources Management (S) Pte Ltd (ERM) to conduct the EIA for the section of the line around and through the nature reserve. The work started immediately and targeted to complete in 2016. The works will include studying the ecosystem and physical conditions along both the straight and skirting alignments, as well as assessing how construction and operation of the line would affect the CCNR. ^[9] The LTA is still studying all options and the final alignment will only be announced near the completion date.

Possible express services in future

The Land Transport Authority (LTA) has expressed interest in the implementation of possible express services on the CRL in future, apart from having just normal services. This express service would benefit commuters during the morning peak hours as trains would stop at only the interchanges and skip the remaining stations, hence, reducing travel time greatly. The plan is currently under feasibility studies and more details would be released once the studies are complete.^[10] |- The under feasible studying of the 50km Cross Island Line could also be merged together with its Thomson-East Coast Line neighbour to the future Changi Airport Terminal 5 and the new industrial zone serving the airport. More details will be announced once engineering studies are completed. -|
