Happy New Year! We hope that your 2026 will be a bright & incredible year for you. The team was rather busy through 2025, especially during the last few months of the year. We weren't able to compile a Snapshot feature to close the year off for updates on the Jurong Region Line (JRL), but will be working to make one happen for this month's progress. To make up for the lack of a Snapshot update though, here are some images that we've come across that may interest you.

We're moving onto recapping the Q1 2025 progress of contract J102, awarded to Shanghai Tunnel Engineering Co. This contract of the Jurong Region Line (JRL) saw several key milestones being hit this past quarter, including but not limited to completion of viaduct segment launching, the commencement of roof frame installation works at the stations and the installation of escalators within the stations. We'll cover these in greater detail as we look at each station site closer.

Continuing on with our 2024 progress report, we now come to the stations under contract J102. Arguably the largest contract under the Jurong Region Line (JRL), the contract stretches across approximately 4.3km from Choa Chu Kang to Tengah and includes 3 stations. Also included in the contract are the bare bones for a future station within Tengah's northeast sector, which we refer to as Forest Hill, after the Tengah planning district in which it is located.
Progress on the contract has seen several milestones through 2024 which include the handover of the first sections of viaduct to the track works contractor, completion of launch gantry Mulan's viaduct segment launching and the completion of all viaduct piers along the contract. We take a closer look at the various sections in detail after the jump.
Today, contractor for package J102 - Shanghai Tunnel Engineering Co (STEC) - released a progress update on the package's official Telegram channel. The update features aerial views from a drone of the project's progress and all four stations (3 full build & 1 future infill) can be seen in the video. We'll go through some of the coverage from the video and accompanying update on upcoming works that was initially published, but subsequently retracted, as well.

We earlier detailed the changes being made to Choa Chu Kang station. Over the past week or so, some of these changes to the existing station's concourse area have been changed. The existing fareline nearer to Exit C has been shifted further out towards Exit A. In addition, the new passenger service centre (PSC) for the North-South Line (NSL) has been put into service, with the old PSC being closed for service.

A lot has taken place in Q2 for contract J102. With 4 stations being built under the contract, we had to split this update into 2 parts to make it more bite-sized and not an overload of information or more of a huge photo dump than it already is. Progress has been swift and moving full steam ahead as the changes to the sites can be seen with every visit. Nonetheless, it will still take some time before the Jurong Region Line (JRL) sections under this contract can achieve basic structural completion.

There has been a lot of work going on at Choa Chu Kang station ahead of the Jurong Region Line (JRL)'s arrival in 2027. All these works will serve to allow the station to increase its capacity for handling commuter traffic. What are the works taking place and how will these help to increase the station's capacity you may ask? We're here to break it down so that you'll be able to better understand the ongoing works.
Modification works at Choa Chu Kang station entail the following:

With Q1 of 2024 coming to a close soon, we're beginning our quarterly updates on the Jurong Region Line (JRL). Last week, we covered the progress of Tengah depot over the first quarter, including the commencement of trackworks! Today, we'll dive a little deeper into the works taking place under contract J102 by Shanghai Tunnel Engineering Co which includes 3 stations, approximately 4km of viaducts and a future shell station.

Work over at Choa Chu Kang station has been barreling along with major progress made over the past quarter. Station columns have gone up and the viaduct piers parallel to the North-South Line (NSL) and Bukit Panjang LRT tracks have sprung up with crosshead construction beginning as well. Be warned, this post is going to be a long one and photo-heavy.

A recent post by MP for Keat Hong divison, Mr. Zhulkarnain Abdul Rahim, showed a visit to the Jurong Region Line (JRL) Project Information Centre (PIC) featuring new station architectural models. Our team made a visit to the JRL PIC today to check out the new additions to the collection.

The past quarter has seen the station site at Choa Chu Kang take shape as rebar is installed and concrete poured. More of the station cable troughs and base slab can be seen being built. Installed rebar gives us an idea of where the facilities such as vertical transport and viaduct columns will go. Most of the work has progressed out of foundation works and will transit to the building of the station structure.

Choa Chu Kang is going to be the station that connects it all - the Jurong Region Line (JRL), North-South Line (NSL) & Bukit Panjang LRT. Works have been on-going for a while now, when the site looked extremely different. Now a multi-storey carpark with commercial units on the ground floor has gone and the bus interchange has shifted to allow for the JRL construction. To say that the place looks different would be an understatement.
We launched our new mini-series last week, a deep dive into the process of building an elevated MRT line which was last seen on the East-West Line when the Tuas West Extension was built. Join us as we explore the first of six distinct stages of bringing an elevated MRT line to life - the preparatory works stage.
Recently we came across several render videos for contract J102. The first video shows the renders of Choa Chu Kang, Choa Chu Kang West & Tengah stations which are being built by contractor Shanghai Tunnel Engineering Co (STEC). Subsequent videos show the process of unloading components of the launch gantry at the storage site, assembly & lifting of the launch gantry used for viaduct construction and the construction of the base slab at Choa Chu Kang station.

The construction of Choa Chu Kang station involves the building of 2 new island platforms to serve the existing North-South Line (NSL) and the new Jurong Region Line (JRL). Work is underway to form the base of the station, which is likely to be one of the few 2-level stations sitting on the ground for the JRL. Most of the JRL stations will feature 2 levels, however the concourse levels should be elevated off street level necessitating the extra footing work before work can begin on the station levels proper.

It has been a while since we've come to Choa Chu Kang and things are progressing fairly well. Foundation works are well under way at the station site where 2 new island platforms are being tacked on to the existing station for the Jurong Region Line (JRL) and to facilitate cross-platform transfers to the southbound North-South Line (NSL) track. Further along, work is also underway for the foundations of the piers towards Choa Chu Kang Avenue 3.

Recently we came across some new renders of the stations along the Jurong Region Line (JRL). We thought it would be fitting to do a re-post of all the renders we've amassed thus far. Do stay tuned as we'll let you know where we got the new renders from after the phase 3 batch.

Its been a while since we caught up to how things are shaping up on the Jurong Region Line (JRL). Things are indeed picking up pace! We've made a few comparisons to how things looked in the past as far as possible. For this post in particular, we'll be covering the stations under contract J102 (Choa Chu Kang, Choa Chu Kang West & Tengah) and also Tengah Park under contract J108.

Contract J102 was one of the first contracts awarded for the construction of the Jurong Region Line (JRL). As such, construction works at this contract are some of the farthest along. The contract entails the construction of 3 JRL stations, including addition & alteration works to the existing Choa Chu Kang station. To do this, a new platform will be added to allow for cross-platform transfer between the North South Line (NSL) and JRL. The concourse level will be expanded as well, to accommodate circulation and vertical access to the new platforms.
