We're back with another snapshot feature on the Jurong Region Line (JRL) to kick off Q3 of 2025. Viaduct-wise, completion status is still the same along the line with 80% of the phase 1 contracts having completed span construction works. Station works are underway, with more stations commencing interior works. Track works have ramped up as well, with more stations beginning to receive rails as installation works slowly expand across the first phase of the network. All the details after the jump.

Phase 1
Over July, we have seen rail installation works reach additional stations at Choa Chu Kang West, Bahar Junction and Jurong West. These are on top of other stations where such works had already passed through previously at Tawas, Gek Poh, Hong Kah and possibly Tengah. Interior works were also commencing, with some cladding becoming visible. Viaduct construction remains a work in progress for contract J103 as there are still multiple sections of viaduct that require segment launching for completion to be attained.

Tengah depot (Contract J101)
In a nutshell: Work was progressing on several fronts at the depot. The administration building, which will house both the Operations Control Centre (OCC) and Depot Control Centre (DCC) has begun the process of window and external facade installation. Over at the rolling stock workshop, rails have been connected to the first few inspection lines. Others will follow suit. Fencing was also being installed to segregate the fully automated operation along the test track from other areas in the depot that operate at reduced speeds. Trackworks were also proceeding up along the reception track ramp, but stopping short of the contract boundary with contract J103. Over at the bus depot multi-storey parking structure, works were coming along with bridge structures completed to connect with the roof level of the rolling stock workshops, where additional parking bays will be located.

19 July 2025

JS1 - Choa Chu Kang (Contract J102)
In a nutshell: The basic structure of the viaducts should be largely completed now that all components are in place for handover to the trackworks contractor. Over at the station itself, roof truss frame installation was nearly completed as works on the installation of the roof coverage components began. Recent reconfiguration works within the station saw the closure of the stairs connecting the NSL concourse with the transfer mezzanine to the LRT station. Presumably, demolition works will begin here to allow for the second pair of escalators between the concourse and mezzanine to be installed. Modification works for the additional lift in the NSL station and pair of new escalators connecting the platform and northern mezzanine are due to complete in Q4 2025.

Further along, where the line crosses over several car park lots, works were underway for the construction of a fire-safe structure below the JRL viaduct. These will serve to protect the line for some time should a parked vehicle below catch fire. These lots are set to be reopened some time in Q4 2025.

27 July 2025

JS2 - Choa Chu Kang West (Contract J102)
In a nutshell: With the roof frame trusses installed, other parts of the station are coming together. Following the installation of escalators at the station's 2 exits, roofing works have also commenced here. Internal installation works and the external facade works continued as well.

27 July 2025

JS3 - Tengah (Contract J102)
In a nutshell: Roofing works at the station appeared to have continued on. Along the viaducts, more sections of the fully enclosed noise barrier have been installed along the reception track that links to the top level.

19 July 2025

JS4 - Hong Kah (Contract J103)
In a nutshell: Externally, the station appears to be mostly the same with the bulk of works taking place internally. Views of the linkbridge exit were obscured from the vantage points that we had visited, although progress has likely been made there.

19 July 2025

JS5 - Corporation (Contract J103)
In a nutshell: Escalators have been installed at 2 of the station's exits, while the third exit facing the Hyundai innovation centre will only feature lift and staircase access. All exits had the roof frames installed, while two had the insulating layers already added in as well. Works were progressing on the station's internal features, with some glass partitions already installed at platform level around the atriums where escalators and stairs connect.

19 July 2025

JS6 - Jurong West (Contract J105)
In a nutshell: Externally, the station does not appear too different. However, when viewed from above and the northern side, one would be able to see ongoing trackworks have reached the station from TSA8 in Gek Poh. Additionally, further glass facade components have been installed at concourse level.

19 July 2025

JS7 - Bahar Junction (Contract J105)
In a nutshell: Progress on the station's satellite building and connecting paid transfer linkway have begun picking up. A temporary protective enclosure was built at the site of the satellite station building to allow trackworks to proceed as the roof frame is installed at the station. Likewise for the paid transfer linkway at platform level, roof frame supports have begun installation work. It is likely that there will be travelators installed at this level judging from the depth of the structure being cast.

19 July 2025

JS8 - Boon Lay (Contract J106)
In a nutshell: Jurong West Street 64's southbound carriageway was reinstated below the station building while works for the reinstatement of the northbound carriageway were in progress. The northbound carriageway would be redirected under the station building in early August. Escalator installation had begun at the southern end of the station between the mezzanine and concourse levels. Along the paid transfer linkway, installation of roof frame supports had commenced.

19 July 2025

JW1 - Gek Poh (Contract J107)
In a nutshell: Roof frame installation works were in progress at the station, with escalator installation also underway. The protective enclosure along the platform allowed for the concurrent track laying works to proceed, with the Choa Chu Kang-bound tracks running through the station. It is not clear if the Peng Kang Hill-bound set of tracks also runs through the station currently as this set of tracks does not emerge south of the station.

19 July 2025

JW2 - Tawas (Contract J107)
In a nutshell: Roof installation works were nearly complete at the station. Casting of the staircases was ongoing, with the locations now becoming clearly visible. Interior works were commencing, with the first installation of cladding through what was likely a test section visible at the station's northern end. Works had begun for the foundations of one station exit at street level.

15 July 2025

Phase 2
As always, phase 2 is a little bit of a mixed bag with some contracts fairly advanced in works while others are further behind. It should come as no surprise that the stations along contract J108 have been making waves with regards to progress, even to the extent of commencing interior fit out works. The contract is also left with 3 viaduct spans to achieve completion of all viaduct span construction works. In contrast, stations along contract J109 were in various stages of progress. Viaduct construction under contract J109 was still a long way away from completion as well.

JE1 - Tengah Plantation (Contract J108)
In a nutshell: Roofing works are ongoing for the the station building. Internally, architectural finishes such as the installation of cladding and ceiling panels was being trialed. External facade sections were also being installed concurrently. Foundation works for the station exits were underway, with the above ground structures to follow shortly. Launch gantry Magnificent Mammoth had also reached the final pair of spans that would link the viaduct with the section built under contract J102. The gantry would subsequently be lowered and disassembled on site - recent information obtained indicates that this would occur from mid-August to September 2025, possibly indicating that the final pair of viaduct spans would not utilise the gantry for completion.

28 July 2025

JE2 - Tengah Park (Contract J108)
In a nutshell: Roofing works for the station have since been completed. Along the linkbridge connecting to the exit in front of Dulwich College, concrete planter boxes have been installed. The staircase sections at the exit have also been assembled.

28 July 2025

JE3 - Bukit Batok West (Contract J108)
In a nutshell: The bulk of the station's structure had been cast, with remaining sections at the eastern end connecting to the viaduct yet to be completed. Roof frame installation works had progressed well and insulation installation was underway. One span for the West Coast-bound viaduct remained to be completed here to connect the station to the viaduct. Parapet wall installation works for the viaduct towards Toh Guan were in full swing while similar works along the viaduct towards Tengah Park were mostly completed.

28 July 2025

JE4 - Toh Guan (Contract J109)
In a nutshell: Formwork was being installed for the casting of the platform level of the station while viaduct construction was underway on either side of the station. Due to the close proximity of works to the southbound track of the NSL, speed restrictions were imposed on trains passing by the worksite. Viaduct span construction works were more advanced at the section north of the station compared to sections south of the station.

28 July 2025

Tracks through Jurong East Integrated Transport Hub (Contract J120)
In a nutshell: Works on the viaduct through was progressing slowly. Parapet wall installation works had completed for the section of viaduct outside the integrated hub building that had been completely cast. One pair of viaduct spans outside the building had yet to commence parapet wall installation. The remaining section of viaducts through the building had not been completely cast, thus parapet wall installation works could not commence on these sections yet.

28 July 2025

27 July 2025

JE5 - Jurong East (Contract J110)
In a nutshell: With the majority of the station structure cast, works commenced on the installation of the station's roof frame. At the existing platforms within the NSEWL station, additional sections were blocked off for modification works to add extra escalators between the concourse and platform levels. Enabling works included the construction of new plant rooms to allow for the relocation of existing services and utilities to create the room required for the new escalators. Access to the station from the Jurong East town centre was also redirected through the future transfer hub annex, allowing for the temporary stairs at Exit A to be removed for the next phase of works.

28 July 2025

27 July 2025

JE6 - Jurong Town Hall (Contract J109)
In a nutshell: All 6 pairs of diamond-shaped roof supports had been installed at the station, along with the frames for both lift shafts. Viaduct span construction was taking place along the West Coast-bound track, with the launch gantry positioned to complete segment launching on this side of the station.

28 July 2025

JE7 - Pandan Reservoir (Contract J109)
In a nutshell: Station casting works were still in progress, with the station building sporting lots of scaffolding support through its length. Casting of the crossheads for the viaduct piers south of the station to allow the line to make a 90-degree left turn were underway. On the viaduct front, approximately 23 spans had been completed by the launch gantry working from the end of the line along West Coast Road.

28 July 2025

Phase 3 (South)
As the phase with the most time on hand, progress along the southern stretch was a little varied. Contract J111 appeared to be the quicker moving of the two contracts, both in terms of station and viaduct construction. Contract J112 had slightly more complex integration requirements due to a vehicular underpass being constructed beneath the Ayer Rajah Expressway and the need to conduct underground works beneath the Jurong Pier flyover, resulting in slower progress along the viaducts.

JS9 - Enterprise (Contract J111)
In a nutshell: Casting works for the station's platform level were fast coming towards completion and internal structures for the various rooms at concourse level were beginning to take shape. On the viaduct construction front, the gaps between piers were fast coming down as significant stretches of span construction approached completion.

19 July 2025

27 July 2025

JS10 - Tukang (Contract J111)
In a nutshell: Casting work for the station was focused on the trackbeds and platform level. Viaduct span construction had also commenced on either side of the station. As there are only a few spans in the vicinity of this station, span construction should not take too long to complete.

27 July 2025

JS11 - Jurong Hill (Contract J112)
In a nutshell: Station pier construction had progressed with 3 of the station's 10 piers completing the installation of pre-cast crosshead segments. A fourth was undergoing the same phase of installation. There were several station piers that were still in the column casting stage. North of the station building, there were several viaduct piers that had been completed. Viaduct span construction began on this section recently. Across the Ayer Rajah Expressway, span construction had been ongoing for some time now and had seen approximately 2 spans completed. Works were underway here in constructing the span abutting the viaduct pier constructed under contract J111, which would be handed back after the completion of span construction by contract J112.

27 July 2025

JS12 - Jurong Pier (Contract J112)
In a nutshell: There was some advancement of the station building's construction, with more columns being cast. Apart from this, construction was underway for the foundation piles for the viaduct piers along Jurong Pier Road.

27 July 2025

Phase 3 (North)
Progress along the northern section of phase three was a lot more homogenous due to the fact that both contracts J113 and J115A were awarded to the same contractor, effectively allowing the phase to function as one big contract as opposed to two smaller contracts. Progress on the stations and viaducts under each contract were roughly on a similar scale.

JW3 - Nanyang Gateway (Contract J113)
In a nutshell: Casting of the platform level was largely completed, with works ongoing at the plantrooms on either end. Casting of the remaining viaduct piers that would support the Choa Chu Kang-bound track had also been completed, with viaduct span construction works to follow soon. In this section of the contract up to the ARC building, there were approximately 10 spans to be completed.

27 July 2025

JW4 - Nanyang Crescent (Contract J113)
In a nutshell: The station building has progressed significantly, with the viaducts on either end of the station fully connected. The majority of casting works for the station building appear to have been completed and component installation (e.g. lift shaft frames, roof frame supports) should begin some time soon. Viaduct span construction along this section of the contract, from NIE to the ARC building, has been completed.

27 July 2025

JW5 - Peng Kang Hill (Contract J115A)
In a nutshell: Most of the station's structure appears to have been cast, with works taking place on the platform and upper concourse levels. Viaduct span construction was progressing towards the west of the station, where the bulk of the viaduct is located. East of the station, approximately 3 viaduct piers are all that will be constructed, with the three having crosshead casting completed recently.

27 July 2025

Trackworks
With structural works for the stations and viaducts attaining structural completion, more and more sections of trackway have been handed over to the trackworks contractor under contract J150. Several temporary staging area (TSA) sites were set up as follows:

TSA 1 - Near Forest Hill future infill station site, next to former J102 casting yard
TSA 2 - Near Tengah Park station
TSA 4 - Near Hong Kah station
TSA 5 - Within Tengah depot
TSA 8 - On site of former Pioneer Primary School

TSAs 1, 4, 5 & 8 were active and facilitating track works along phase 1 of the line. All stations, except Choa Chu Kang, Corporation & Boon Lay had received some sections of tracks within their respective sites.

TSA1 - Forest Hill
In a nutshell: Works on rail installation have resumed, extending through Choa Chu Kang West station on the Choa Chu Kang-bound track. Installation works are currently taking place just east of the station building, with the automated lifter being used to lay track sections where rails have already been attached to sleepers.

27 July 2025

TSA8 - Gek Poh
In a nutshell: Track laying works have extended as far as Jurong West station on the Choa Chu Kang-bound track. A works train was also seen pushing additional sections of rail towards the automated lifter, seen at the Jurong West station platform, to continue rail laying works.
