J150 - Trackwork update Q1 2025

8 March 2025 - A sleeper-laying machine on the Jurong Pier-bound track near Hong Kah station.

Track laying and related installation works - referred to as Track Related Installation Programme (TRIP) - commenced on the Jurong Region Line (JRL)'s main line following the handover of sections of viaduct near the Tengah Junction by contract J102 in August 2024 to the trackworks contractor under contract J150. This represented the first contract where viaducts were handed over for TRIP purposes. TRIP works will encompass the laying of rails (both running rails and the third rail as well), cabling for communications, signaling infrastructure and platform screen gates among other components. For this post, we'll look specifically at the rail laying component as this is among the first activities to be initiated under TRIP works as locomotives and wagons will use the installed rails for subsequent installation activities.

J108 / Tengah Plantation, Tengah Park & Bukit Batok West - A 2024 progress report

We've been on a journey re-looking back at the progress made through the year at the various Jurong Region Line (JRL) contracts. Thus far, we've gone through the phase 1 contracts, which you can view here:

• Contract J101 for Tengah Depot
• Contract J102 for Choa Chu Kang, Choa Chu Kang West & Tengah stations
• Contract J103 for Hong Kah & Corporation stations
• Contract J105 for Jurong West & Bahar Junction stations
• Contract J106 for Boon Lay station
• Contract J107 for Gek Poh & Tawas stations

Having completed the rotation of phase 1 contracts, we now venture into phase 2 territory. These stations will open a year later than their phase 1 counterparts and will serve a separate service on their own, unofficially called the eastern route, which consists of 7 stations. The first contract along this phase is Contract J108, which was awarded to a joint venture between McConnell Dowell & John Holland.

Milestones attained by this contract thus far have included the completion of casting all precast segmental boxes for viaducts, the commencement of roof frame installation works at two (2) stations and the commencement of linkbridges connecting to station exits at one (1) station. Of the phase 2 contracts, this one is slightly ahead of the others. More details after the jump.

An overview of contract J108 stations at Tengah Plantation (top), Tengah Park (middle) and
Bukit Batok West (bottom) as of end-Q2 in June 2024.

Over Q2, contract J108 has seen the stations at Tengah Plantation & Tengah Park continue to take shape. Work at Bukit Batok West has also began to speed up with the structure of the station becoming more visible as more station columns are cast. Viaduct construction work also pushed further into Tengah. while causing some road diversions, ultimately inching towards completion. Other developments were also made in completing the various spans using the launch gantries Rock Steady and Magnificent Mammoth. More information after the jump.

Contract J108 is the first of two contracts that cover three stations each - the other being neighbouring contract J109 which we'll be covering in the following post. Over the first three months of the year, work has been chugging along with viaduct spans taking shape and the station buildings slowly being cast. We take a closer look at the three stations under this contract - Tengah Plantation, Tengah Park & Bukit Batok West - in greater detail after the jump.

J108 - Tengah Plantation, Tengah Park & Bukit Batok West update Q3 2023

Stations under contract J108 as on 24 September 2023.

A lot has happened last quarter over at contract J108 which is for the construction of 3 phase two stations at Tengah Plantation, Tengah Park & Bukit Batok West. Also part of the package are viaducts from Tengah Junction, where the line diverges from the western route, up to the interface with contract J109 along the Pan Island Expressway (PIE), south of Bukit Batok town. In order to speed up the updates ahead of the year-end recap that we're in the midst of preparing, we're updating the rest of the line by contract. Head on past the jump for loads of pictures about the progress made over Q3 2023.

Having cleared our updates on the quicker-moving phase 1 of the Jurong Region Line (JRL), we're now starting our updates on the 7 stations that will form phase 2 of the line. The first of these is the hardest to reach - Tengah Plantation - which is sited in the middle of Plantation Crescent in Tengah new town. There is good news though, as the area is set to open up from around August with the home owners receiving their keys shortly. This means that the area will gradually become accessible in addition to having several vantage points from which the construction can be observed. We'll definitely be making use of these to bring you some updates.

Yesterday, the second launch gantry for contract J108 was raised into position south of Tengah Park station. The gantry will begin work assembling the viaduct spans for the cripple siding located here. The lifting process utilised 2 mobile crane units that lifted the gantry in a process known as a tandem lift. Once elevated to the desired height, the cranes swung the gantry over to the final position atop the supports and the gantry was locked in place.

J108 - Tengah Plantation coming up

 Tengah Plantation station under contract J108 is one of the quickly up and coming stations on the Jurong Region Line (JRL). As of 9 January 2023, the crossheads for the concourse level are being constructed along with some columns that will support the track beds. During the recent ground breaking & viaduct construction segment launching ceremony held by the Land Transport Authority (LTA) on 13 January 2023, several images were released showing several cross sections of the JRL stations. One design in particular, shows a station within a road median - similar to the design that will be used at Tengah Plantation station.

Contract J108 is for the construction of 3 stations on the Jurong Region Line (JRL), however we will only be covering the 2 stations within Tengah for this contract in this post. No worries, the next station will be covered in the following post so no losing out there. While contract J108 may fall under the second phase of the line, works at this contract are progressing at lightning speed.

Phase 2 of the Jurong Region Line (JRL) is the final phase we cover in our update for Quarter 3 of 2021. This phase consists of 4 contracts - J108, J109, J110 and J120 for the construction of various parts of viaducts and stations. Contract J108 was won by John Holland-McConnell Dowell and will connect phase 2 to the rest of the line at phase 1's Tengah interchange station. The contract will involve the construction of 3 stations at Tengah Plantation, Tengah Park & Bukit Batok West.

As this post is rather photo-heavy, we have decided to break the post up according to contract for easier readability. Do look out for our subsequent posts on other sections of the line.

With the release of tender bidding for contract J109, all contracts for phase 2 of the line have been floated for tender.

Pre-Construction - Tengah, Hong Kah & Tengah Plantation

Being built as a new township, Tengah estate will see several Jurong Region Line stations serving the different districts within the town. Tengah station is to be located at the town centre, Hong Kah station will serve the southern portion while Tengah Plantation station serves the plantation residential district. In future, another station may be added further north between Tengah and Choa Chu Kang West stations to serve the north eastern portion of the town. All of these stations lie within a currently heavily vegetated area and works are underway to clear the area for construction activities to commence on the new town.
