Second stretch of Rail Corridor to be closed on 19 September

6 09 2016

The second stretch of the Rail Corridor being affected by the Murnane Pipeline Project, which extends from Commonwealth Ave all the way southwards to Tanjong Pagar Railway Station, is being closed to the public from 19 September 2016.

A section within the stretch, from Jalan Kilang Bahru to Tanjong Pagar, will remain closed until the pipe laying project is completed. Its reopening is scheduled for the fourth quarter of 2019.

Work has already commenced in the initial  section that was closed. The final section affected, from Jalan Anak Bukit to Holland Road, will close later this year.

Beside the closures affecting the Rail Corridor, work on the final stretch of the MRT’s Circle Line will see Tanjong Pagar Railway Station closed from next year. The station, under which the MRT line is being run, will only reopen in 2025.

Update on closure of the Rail Corridor

24 06 2016

The first stretch of the Rail Corridor affected by the Murnane Pipeline Project, will be hoarded up and closed from Monday 27 June 2016. The stretch is  from Holland Rd (near Greenleaf Estate) to Tanglin Halt Road (including the former Rail Corridor Art Space). Exact dates for the closure of the remaining stretches affected (see graphic below), which are scheduled for the third quarter of 2016, are still being worked out. The corridor will be reopened in parts as work is completed from the end of 2017 to the end of 2019. More information on the project and the how the Rail Corridor could be affected is available in some of my earlier posts:

Goodbye for now my friend

3 06 2016

Like a thief in the night, change in Singapore comes swiftly and suddenly. One big change, albeit temporarily, that will soon be upon us, involves yet another space I have a fondness for. This is the stretch of the former rail corridor between Bukit Timah Road and Holland Road. The greenest part of the Green Corridor, as the very green rail corridor has been christened by the movement calling for its preservation as a green space, it has been one the the few escapes I am able to find from a Singapore that has been over concretised. While the work is not meant to leave a permanent scar on the Green Corridor, the changes it may bring to the corridor visually could take many more years before it regains the appearance of the world I had grown to love.

Work will soon begin to lay a pipeline that is intended to address the growing city centre’s needs far into the future. Some 11 kilometres of the former corridor will be affected stretching from Rifle Range, where the Murnane Service Reservoir is, southwards to Tanjong Pagar Railway Station (which will itself be closed off from 2017 to 2025 for the construction of a Circle Line MRT Station below ).

The affected parts of the corridor will be closed off in phases, commencing with the stretch between Holland Road and Commonwealth Avenue in the later part of June 2016 with the other stretches being closed from te third quarter of 2016. The various stretches will be reopened as work is completed with the Holland Road and Commonwealth Avenue stretch’s opening scheduled for the end of 2017. The stretches between PIE / Jalan Anak Bukit and Holland Road and Commonwealth Avenue to Jalan Kilang Barat are scheduled to reopen by the fourth quarter of 2018, while the southernmost stretch of the corridor will be the last to reopen at the end of 2019.

First announced close to two years ago in June 2014, one of the tasks before work was to start was the development of an Environmental Impact Statement (EIS) to look at possible impacts and recommend mitigation measures during the period of pipe laying. An environmental consulting firm, CH2M Hill Singapore Consulting Pte Ltd, was engaged to carry this out and also to develop an Environmental Monitoring and Management Plan (EMMP). This, as members of the Rail Corridor Partnership who attended a briefing on it earlier this week had understood, has been accepted by the various Government agencies involved.

While EISs and EIAs  may involve qualitative identification of threats and assessments of the severity of their impacts, and contain an element of subjectivity, they have an important role to play in the management of invasive activities in environmentally sensitive areas. In the case of the pipeline, work is certainly needed, and having an EIS carried out is better that not having one done at all.

Another heritage structure, to which impact is avoided, the truss bridge at Bukit Timah. Here the pipejacking method will be employed and the pipeline will be run deep underground, under the Downtown MRT line.

One key finding of the EIS was on the impact the initial planned routing of the pipeline in the vicinity of Murnane Reservoir would have had on the flora nad fauna rich area of dense secondary forest through which the pipeline was to be run (on the opposite side of Rifle Range Road). This prompted a rethink, which involved much effort, to have the pipeline’s path altered to avoid the secondary forest. In most instances, impacts following mitigation measures are maintained at negligible to minor, with the a few exceptions.

One especially sensitive area identified by the EIS is in the Holland Woods area, just south of the former Bukit Timah Railway Station, which contain several fauna hot spots. Several unexpected species of animals were recorded during the survey carried out as part of the EIS, including the Malayan Giant Frog and the Civet. The impact to fauna in this area after mitigation is expected to be moderate. In all, some 188 species of fauna were recorded, 11 of which are non-native, with 458 species expected. Other impacts considered, include that to the landscape, airborne noise, ground borne noise and vibration, damage to waterbodies as well as to commercial and recreational activities.

Disruption to users of the rail corridor such as walkers, joggers and cyclists, will be minimised throughout the construction period.

Beyond the laying of the pipeline, the former rail corridor will probably be the subject of redevelopment efforts aimed at preserving it as a continuous green corridor that will at the same time be of use to the wider community. Based on the information previously provided by the Urban Redevelopment Authority overseeing this, the detailed design for a 4 kilometre signature stretch from Bukit Timah Railway Station (BTRS) to Hillview Road area. The outcome of this, which would have taken in public and stakeholders’ feedback, and the visual impact it will possible have on the corridor, is yet to be seen.

Information received from PUB:

The PUB will be commencing work for the laying of Murnane Pipeline Project (see also : The Rail Corridor that will be forgotten) in the 2nd quarter of 2016. Half of the pipeline will run beneath the Rail Corridor. The works will be carried out in phases and is expected to complete by 2019. For public safety, PUB will temporarily close off the stretch of the Rail Corridor south of Holland Road during this period, and progressively reopen sections from the 4th quarter of 2017 after the pipeline has been laid and the ground reinstated.  The rest of the Rail Corridor will remain open to the public.

Another new journey along the Rail Corridor

30 06 2014

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.

Disruption to users of the rail corridor such as walkers, joggers and cyclists, will be minimised throughout the construction period.

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.
