Bit by bit, the Tengah depot - home of the Jurong Region Line (JRL)'s trains and operations, is inching towards a semblance of completion. The depot is one of the keys to enabling the line to function and be commissioned. Without the depot, it becomes a tremendous task to ensure that all the line's systems are able to integrate and function collectively as the line is commissioned ahead of opening. In the months prior to the line's opening, testing of the rolling stock (trains) will need to be done within the depot. This process requires the stabling shed, workshops, test tracks and operations control centre to be ready.
At present, none of these buildings are in a state ready to receive any units of the rolling stock. There are no paved roads within the compound to facilitate the delivery of the rolling stock either. Based on how the site looks, the stabling yards may be the first buildings to be ready for the delivery of the rolling stock. In this post, we'll take a deeper look at the progress made at the depot over the past quarter and size up what needs to be done to get it in basic shape for rolling stock delivery to happen.
Over the past quarter, the completed structures at the depot remain similar - the load centres where the power equipment will be located. And that's about it. All remaining support structures are still in the midst of structural construction. These include:
- Stabling sheds - located right at the back of the site, near the Kranji Expressway
- Rolling stock workshop - located to the left of the site, near the Pan Island Expressway (PIE)
- Operations Control Centre - located to the left of the site, near the front access road
- Bin centre
- Train wash plant - located along the reception tracks, near the workshops
- Test track
- Permanent way workshop
- Reception track ramp
- Staff parking area
- Guard house
Trackworks have commenced in the areas in front of the rolling stock workshop and stabling shed while structural works are ongoing concurrently to speed up the process. One of the factors that adds to the complexity of the build for the depot is the co-location of other facilities such as the integrated bus depot and foreign worker dormitories on the site. Nonetheless, as the main structures for the rail system are critical to the line's commissioning, greater emphasis is being put on these for earlier completion.

Reception track ramp
The reception track ramp serves to connect the depot which is being built at ground level with the elevated viaducts of the main line. Over the past quarter, steady headway has been made with the casting of the ramp structure. By the end of the quarter, the structure was pretty much complete and ready for the viaduct span to connect under contract J103.
 |
| 13 April 2024 - Portions of the reception track ramp being progressively cast in early-Q2. |
 |
13 April 2024 - Casting involved setting up the formwork, installation of rebar & tendons and
pouring of concrete. |

Rolling stock workshop
The rolling stock workshop is a key facility required for the testing of trains before they can move onto dynamic tests along the tracks. It is here that engineers are able to lift the train consist to iron out any kinks that may require adjustments during the static testing phase. Work on the rolling stock workshop has seen some progress but is slower when compared to that of the stabling shed. The rolling stock workshop also required excavation below the ground level in order to create the inspection pits through which the engineers can access the train's under-carriage equipment. The top level of the rolling stock workshop will also be used to house buses as part of the bus depot.
In front of the rolling stock workshop, trackwork had commenced several quarters back in a bid to have work performed concurrently to make up for time lost due to the effects of the Covid pandemic. Work has progressed to lay the various lines that will connect with the tracks within the rolling stock workshop. This process includes the leveling of soil, laying of ballast, positioning of sleepers & cable troughs and the laying of the flash-butt welded steel rails. As far as we can see, the electrified third rails have yet to be laid.

Stabling shed
Another key facility required for the line's early testing efforts is the stabling shed. This single structure will be able to house up to 100 trains for the line. As the rolling stock workshop's purpose is to perform maintenance on the trains, it has a lower capacity aimed with less tracks as its role is to perform maintenance work. The stabling shed allows trains to be parked and stored when not in use and hence has a greater capacity.
Work on this facility is showing promising signs with structural construction on the western end reaching the top and roof levels. Trackwork has also begun in front of approximately 2/3 of the facility. These will serve to allow the trains to enter the respective stabling tracks where they can be shut down and parked for the duration where they are not required in service.

Operations Control Centre (OCC)
The OCC forms the nerve centre of the line, from which the position of all trains is tracked and signals given to operate the line. Gradually over the past quarter, the base of the OCC has began taking shape. With piling work completed previously, the footings for the individual building columns were being cast and rebar for the base of the columns installed ahead of further works as the building progresses.
