It was three years ago on 30 June 2011 that we waved goodbye to the Malayan Railway and its 79 years of trains running through to Tanjong Pagar Railway Station. The cessation of train services freed up a 26 kilometre long corridor that cut a north-south path through Singapore, land which the Singapore government has committed to maintaining as a continuous green corridor for the benefit of the wider community.
The Rail Corridor, which does have the potential to serve as a connector in more ways than one, including the provision of an unbroken link running down from the top of Singapore right into the heart of the city, as well as a green link for flora and fauna between the Bukit Timah Nature Reserve and Central Catchment Reserve with the green belt at the Southern Ridges; will now also see use as a connector for a new set of water pipes that will carry water from the Murnane Service Reservoir into the city area, required to be laid to meet future demands, as well as allowing for the replacement of an ageing set of pipes.
The project, which was presented by the Public Utilities Board (PUB) to the members of the Rail Corridor Partnership (RCP) on Saturday and to members of the media today will involve a 11 kilometre stretch (about half of the total length of pipes to be laid) of the southern section of the corridor from Jalan Anak Bukit to Tanjong Pagar and is scheduled to commence shortly. The project will start with the PUB first carrying out a detailed engineering design from July 2014. This will be followed by an Environmental Impact Assessment that will take place from December 2014 to August 2015 as well as Soil Investigations.
The project’s construction phase will follow the calling of a tender in October 2015, with work starting in April 2016 at a section running from Holland Road to Commonwealth Avenue using a cut and cover method involving the digging of an open trench a rate of one length of pipe laid per day. This section is scheduled to be fully reopened in October 2017.
Construction is expected to be completed by September 2019 with work along the stretch from Jalan Anak Bukit to Holland Road scheduled for completion in March 2018, the stretch from Commonwealth Avenue to Jalan Kilang Barat completed by September 2018 and the last stretch from Jalan Kilang Barat to Tanjong Pagar completed by September 2019. Throughout the construction period, access to the rail corridor will be maintained, and alternative paths will be provided to allow users to continue with their activities where necessary.
Due consideration has also been paid to the historic features along the route of the intended pipeline such as Bukit Timah Railway Station (BTRS), the truss bridge over Bukit Timah / Dunearn Road as well as a brick culvert close to BTRS with pipe-jacking used in way of the bridge and culvert. In way of BTRS, the pipeline will be run in the area behind the station.
Members of the RCP, including representatives of Nature Society (Singapore), are generally supportive of the project. It is worth taking note that as in the case of the Central Pipeline Reserve, the laying of the pipeline along a stretch of the corridor would provide for it being kept free from development and hence, the preservation of the stretch of the rail corridor as a uninterrupted green corridor following the completion of works. Plans for future use of the rail corridor has been the subject of much interest since the closure of the railway. As yet, the future use of the corridor has not been determined, although there is that commitment to preserve it as a continuous green space. A much anticipated design competition, expected to have some influence on its future use, is expected to be announced in the near future.
