The DEIA report of Sungai Buloh – Serdang – Putrajaya Line has outlined the alignment options for KVMRT Line 2.
The preferred alignment then was decided based on an evaluation of various factors including the route should improve connectivity to present and future major developments and to areas that have potentially high ridership, the route must facilitate regeneration in areas such as the Batu Kentonmen area, Tun Razak Exchange development and Jalan Cochrane redevelopment.
The route should provide connectivity to existing/ planned railway and public transport systems including the KTM Komuter, LRT and monorail lines, should utilise highway land and other government reserves so as to minimise private land take and lastly the social and environmental impacts should be kept to a minimum.
The above is MRT SSP Line proposed alignment during the public viewing session.
Technical information
As precedent to SBK Line, two different structures will be used; elevated guideway and tunnel for underground.
A key decision for the SSP Line is the extent of elevated track. It would be inappropriate for the railway to be either completely elevated or completely underground. An elevated railway through the centre of Kuala Lumpur would significantly detract from the quality of the streetscape, and would almost certainly be impracticable in any event.
On the other hand, a completely underground alignment would increase both the capital and operating costs of the line. The railway needs to be cost-effective, and a fully underground alignment would be difficult to justify financially or economically. A secondary point is that travel on the railway is more pleasant above ground.
Where to make the transition from elevated to underground is an important question because transitions take up a great deal of space, and it is difficult to find suitable locations.
