Wrapping up May is an update on the DTL's extensions. Following the base line's completion in 2017, extensions at both ends of the route were subsequently announced, adding a further 6.2km to the route's length. On the eastern end, Xilin station is being added as an intermediate station along a 2.2km extension to Sungei Bedok.

Work was ongoing at all three of Xilin station's exits, which have finally taken shape. In particular, Exits 2 and 3 appear to be more substantially completed and ready for use. Exit 1 was a little further behind in readiness. More shockingly, though, were that some ancillary structures along Changi South Avenue 3 appeared to still be undergoing structural casting works. Nonetheless, the station is expected to open by year's end, with testing on the DTL expected to result in early closures and late openings from next month.

Over in the northwest, the line is also being extended by a further 2 stations, with a 4km alignment bringing the route to a second interchange with the NSL in Sungei Kadut. Site clearing works were underway for both station sites, with the intermediate station site seeing buildings fully levelled. Demolition works were ongoing at the Sungei Kadut station site, although the primary area where the station structure will sit has since been cleared.

Next to the housing blocks at Senja, a docking shaft will be constructed to allow tunnel boring machines to connect new tunnels with the existing line's terminating points. Advanced works for utility diversion are ongoing, with the site not yet handed over to the civil works contractor.

In the unlikely event that you may not have heard, the first CR151 train set for the CRL has arrived on Singapore's shores. The Land Transport Authority – We Keep Your World Moving released a video today detailing new features about the first CRL train to be shipped here. These include larger gangways, more doors compared to existing trains (except the TEL trains) and yada yada yada... We noticed other things.

1. Set 2 appears to be the first set to be shipped here
Shots of the train on the trailer show that the car is numbered 50025. We take this to mean that this is car 5 of set 2, based on other numbers we've seen in this video.

2. A new design feature is the arrangement of the overhead handle bar
In renders previously released, it was a simple pole that ran in a straight line through the centre of the car. It now appears that near the doorways, the bar splits into a rectangle, presumably so that more people can hold on at the same time.

3. At least 3 sets have been constructed
Another shot in the video shows a car numbered 50031. Based on the train car numbering pattern in #1, we figure that this should mean car 1 of set 3.

4. Green colour & LED strip lighting options confirmed
We spied the green colour seats in one of the shots, and right at the end of the car, LED strip lighting near the gangway. The LED strip lighting is unlikely to serve any meaningful purpose other than, well, looking different probably.

The train will be moved from the Jurong Port to the Singapore Rail Test Centre (SRTC), where it will undergo local testing & integration works. As it will still be some time yet before tracks are laid along the CRL and at Changi East depot, the train will likely call the SRTC home for some time yet.

Did you spot the details that we did? How many did you know and how many were new to you? Let us know in the comments.

With the CCL almost ready to open, testing & commissioning works have shifted to the TEL to operationalise phase 5 of the line. Early closures on Fridays and late openings on Saturdays began last weekend as integrated testing commences. We checked in at the two phase 5 stations as well as the modifications to expand Tanah Merah as part of the TEL Extension.

Along TEL5, there aren't many changes, as expected. Given that structural works for the two stations have been substantially completed for some time now, there were minimal and insignificant changes to the general vicinity of the stations. Most notable is the installation of station signage at Sungei Bedok station. Where previously signs were left blank, the information is now visible for passers by to see.

Over at Tanah Merah, works at Exit 4 appeared to be catching up to those of Exit 3, with cladding of the structure substantially completed, along with ongoing roofing works. Part of the sidewalk here had been closed to pedestrian traffic, with diversions in place to allow works to continue.

At platform level, demolition of the former plant rooms at the eastern end of Platforms C through F were in progress. By end-May, demolition works appear to have been completed for both sets of platforms. With these works completed, it may be a matter of time before Exits 3 and 4, along with the new eastern concourse, can finally open for public use.

Last week, the LTA published the first tender for the JRL's West Coast Extension (WCE). Contract W1007, for the detection of utilities as a service, will be due for completion by September 2029. Major thanks to for pointing us to the Indicative Government Procurement Listing that may be updated at the start of each financial year (FY). The listing showed two contracts that may be called this FY in relation to the WCE.

The listing also showed us that the contract numbers would use the prefix 'W' in front of the contract numbers, a move that first began with contracts for the TEL back in 2012. Additionally, it appears that contract W1005 listed on the indicative listing was later renumbered to W1007, signaling that changes to the contracts may still be possible.

3 months since our last snapshot of CCL6 and we've gotten a preview and line opening date. We check in on the line again before preview and opening day to find out just how things are progressing along.

Of the 3 stations, Keppel and Cantonment are the most ready, with all station exits displaying the station name signs and public transport logo caplet. At Keppel, mock locality maps have been put up to provide installers an idea of which information boards are to be updated. At Cantonment's Exit 2, a system map was seen in one of the information boards, while the remainder were still empty.

At Prince Edward Road, neither of the two station exits had the name signs installed yet, although both were sporting the public transport logo caplet. Some works were still ongoing for the architectural features at the exits, along with the installation of covered linkways from Exit 2 to the Shenton Way bus terminal.

Reinstatement works were largely completed for contract 886, which involved the cut & cover tunnels between Prince Edward Road & Marina Bay stations, including the turn back siding that extended up to Park Street. The escape stair shaft was clearly visible now and still fenced off from the main street.

Full loop testing was also in progress, with trains on the Marina Bay branch traversing through the full loop. Trains on the Dhoby Ghaut branch, on the other hand, terminated at Stadium. This is likely to be the off-peak arrangement, with peak hours seeing the trains turning back at Prince Edward Road, using the turn back sidings. LED arrival boards at the CCL6 stations also showed how the display format may change, with services denoted as running clockwise or anticlockwise. It is likely that the next interchange station will be displayed, similar to that of the platform screen door signage, unless the train terminates at a terminal.

It has been close to a month since the Sengkang LRT's West Loop inner track service has been closed for track modification works. How have works progressed in the time? Why are these works even necessary?

Since we last checked in, works have progressed with the demolition of the viaduct parapet walls to allow for connection works to take place. The concrete plinths which form the running surface for the LRT vehicles has also been demolished to make way for the new connections at two points between Layar & Tongkang stations.

These works are necessary as the LRT system was originally designed with a single switch point between the two track directions in the form of the sole cripple siding between Tongkang & Renjong stations (refer to Slide 9). As the Sengkang depot supports operations of both the Sengkang & Punggol LRT loops, this means that the withdrawing of trains from the Punggol system would interfere with operations of the Sengkang system a fair bit. Trains returning to the depot (labelled SKD) would need to proceed along the Sengkang West Loop inner track from Cheng Lim to Tongkang stations, before entering the cripple siding to switch directions.

To alleviate this bottleneck, new reception tracks that would allow trains to bypass this section are being built between Layar & Tongkang stations (Slide 10). Works are more complicated due to the base design of the LRT system, which uses an automated guideway transit system design found in Korea & Japan. Trains use guide wheels that interact with lateral guide rails. Command & control are established through a Automatic Train Operations / Train Detection (ATO/TD) loop panel that runs between the concrete plinths.

When modifying the tracks, the existing concrete plinths need to be demolished to accommodate this ATO/TD loop which needs to pass through the concrete plinth surface. This is why significant demolition works are required at the new connection points. Good news is that the demolition works have appeared to have made good progress thus far.

Last week, we took a look at the progress made along the CPE section of the CRL. Today, we're checking in on progress made along Phase 1 of the line - specifically between Pasir Ris East and Ang Mo Kio stations.

Station works are progressing well, with most stations now at the excavation stage. Due to the built up environments where the stations are located, techniques that enhance stability of the site are employed during construction - this means that the excavation method used is the top-down method.

In this method, excavation and slab casting are performed concurrently, unlike in the bottom-up method where these are done sequentially. Essentially, it is akin to constructing a layered cake where excavation proceeds and then a layer of the permanent structure is built before excavation continues on downwards. In this process, the top slabs can be clearly seen but it gets progressively more difficult to view as the layers proceed down.

On the tunneling front, 16 out of 29 drives have been completed, representing completion of approximately 55% of tunneling for Phase 1 of the line. We can expect that some additional drives may be completed within the next 1 to 2 months as several TBMs near their destinations.

Earlier this week, the Land Transport Authority floated the first tender for engineering feasibility studies for the Seletar-Tengah Line (STL). Contract S1006 is the first contract to be floated for the line and is due to be completed in roughly 5 years in 2031.

Following the engineering feasibility studies, there are likely to be other contracts to be floated for soil investigation, advanced engineering and mechanical & electrical consultancy works. These contracts may take some time to be published nonetheless.

In the blink of an eye, another month has past! We're here this week with an update on the progress made along the CPE. Some highlights include the arrival of TBM Elizabeth under contract P103 at the boundary of Riviera station and the lowering of the TBM for contract P102 ahead of tunneling works commencing. Excavation works have commenced at Punggol station across various sites while slab casting is underway at Elias. That was a lot to unpack. More to come!

Elias station - The diaphragm walls for the main station box area have mostly been completed, with works ongoing for diaphragm walls at the station exits and connecting subways. These works will run up to 2027. Hoarding and noise barriers were being installed at the location of the station's Exit 2 site, located in a corner of the former Siglap Secondary School's field. The TBM shield was no longer visible at surface level and a large crawler crane was noticed near the launch shaft area, indicating that TBM assembly was conducted not too long ago and tunneling works should be commencing soon.

Riviera station - Diaphragm wall works were still underway near the eastern end of the station, closer towards the LRT station. These would allow the connecting subway and station exits to be constructed here. Of note was a sign stating "TBM Cutterhead here" which indicated the arrival of TBM Elizabeth from the launch shaft, just outside the station box diaphragm walls. The team may be waiting for the site above to be cleared before the TBM proceeds to continue its journey through the station box and onwards to Punggol.

Punggol station - Works were at varying levels of progress, with a section of Punggol Walk recently close to facilitate construction of Exit 5. Diaphragm wall construction works had yet to begin at this section. Elsewhere, excavation works were underway with struts installed at some locations of the station box site.

18th April 2026 was the last day of the Sengkang LRT's West Loop inner track service for roughly 6 months. During this period, service on that track will be suspended to allow for connection works of the new reception tracks connecting to the expanded Sengkang LRT depot to be carried out.

Hacking of the concrete plinths that form the running tracks for the rubber tired vehicles will need to be done before the new turnouts can be built. This undoubtedly takes more time than simply replacing the entire pre-assembled section of tracks that we have become accustomed to during MRT track modification projects that have been carried out over the years.

The team took a look at the existing condition of the tracks and progress of the new turnouts on the last day of service before the suspension kicked in. Parapet walls near the junction points were still in place while the last few metres of track on the reception track viaducts had not yet been cast either. The first works that are likely to be carried out will be the modification of the electrical systems to de-energise the affected areas of track, allowing works to be carried out. Subsequently, the guiding and power rails will need to be removed before the parapet walls can be demolished to facilitate connection works.

We will check in periodically during the duration of the works and aim to provide updates on the progress where possible. In the meantime, drop by the SGMC YouTube channel for forward and rear views of the existing track on the last day of operations - link in bio.
