The RTS Link is designed to carry up to 10,000 passengers per hour in each direction, using eight four-car trains of 600+ passengers each, running about every 3.6 minutes at peak. That is a major step up from the Shuttle Tebrau (fewer than 10,000 passengers a day) and a meaningful share of the roughly 300,000 daily travellers at Woodlands Checkpoint. It will not empty the Causeway, but it gives commuters a fast, predictable rail option that skips the road queue entirely.
RTS Link capacity is the number that decides whether the new Johor Bahru–Singapore rail line becomes a genuine commuter backbone or just a nice extra. With passenger service targeted for February 2027 (LTA and Malaysia’s Ministry of Transport, October 2026), buyers, renters and daily commuters are asking the same question: how many people can it actually move, how often will trains run, and will it really ease the Causeway jam? This guide works through the official numbers, compares them with today’s traffic, and explains what the capacity means for homes within walking distance of Bukit Chagar station, such as Causewayz Square in JB City Centre.
If you are new to the project, our simple explainer on what the RTS Link is covers the route and stations, and the RTS Link opening date guide tracks the timeline. Here we focus purely on capacity, frequency and congestion.
RTS Link capacity: the key numbers
The headline figure is up to 10,000 passengers per hour per direction (pphpd), confirmed repeatedly by Singapore’s Land Transport Authority (LTA), Singapore’s Ministry of Transport (MOT) and Malaysian officials. Everything else in the system, from train size to station design, is built around that peak number.
| Item | Figure | Source |
|---|---|---|
| Peak capacity | Up to 10,000 passengers per hour per direction | LTA, MOT Singapore |
| Fleet | 8 four-car trains, each carrying 600+ passengers | MOT Singapore / LTA |
| Peak headway | About one train every 3.6 minutes | Malaysia Transport Minister (Apr 2026) |
| Journey time | About 5 minutes, Bukit Chagar to Woodlands North | MOT Singapore |
| Expected daily riders at opening | About 40,000 commuters | MRT Corp projection (Malay Mail, Aug 2026) |
| Immigration | Co-located CIQ: clear both countries at departure | LTA, MHA Singapore |
| Passenger service target | February 2027 | LTA–MOT joint release, 2 Oct 2026 |
Two points are worth remembering. First, “per direction” means the line can move up to 10,000 people into Singapore and, at the same time, up to 10,000 people into Johor Bahru each hour. Second, 10,000 is a design peak, not a daily total. Actual ridership will depend on fares (not yet announced), timetables and how quickly commuters change their habits.
How frequent will RTS trains be?
At peak, trains are expected roughly every 3.6 minutes, which works out to about 16 to 17 trains an hour in each direction. Multiply that by a train load of 600 or more passengers and you arrive at the 10,000 pphpd design figure.
The simple capacity maths
- 60 minutes ÷ 3.6 minutes ≈ 16.7 trains per hour per direction
- 16.7 trains × about 600 passengers ≈ 10,000 passengers per hour per direction
- A three-hour morning peak could therefore move up to about 30,000 people towards Singapore, with spare capacity in the opposite direction
With a 5-minute ride and trains this frequent, waiting time on the platform is short. For most commuters, the bigger variable will be how quickly they move through the immigration halls, which is why both governments have invested heavily in automated clearance at the stations. Our guide to customs at the RTS and how co-located CIQ works covers that in detail.
Off-peak frequency
Off-peak timetables and operating hours have not been published yet. It is reasonable to expect lower frequency outside rush hours, as on most urban lines, but buyers should wait for the operator, RTS Operations Pte Ltd, to release the official timetable before planning around specific times.
How does RTS Link capacity compare with today’s Causeway traffic?
The RTS Link adds a large block of rail capacity to a crossing that currently relies mostly on roads. The fairest comparison is with the existing rail shuttle and with total traveller numbers at Woodlands Checkpoint.
| Measure | Figure | What it tells you |
|---|---|---|
| Woodlands Checkpoint travellers | About 300,000 per day; up to 340,000 on long weekends and public holidays | Total volume across all modes, both directions (MHA Singapore) |
| KTM Shuttle Tebrau maximum capacity | Fewer than 10,000 passengers per day | The current rail link (MOT Singapore) |
| RTS Link peak capacity | Up to 10,000 per hour per direction | Roughly the Shuttle Tebrau’s daily maximum, every hour, each way |
| Expected RTS riders at opening | About 40,000 per day | A projection, roughly one in eight Woodlands travellers |
Put simply, the RTS Link moves in one hour what the Shuttle Tebrau can move in a whole day. LTA’s 2018 factsheet noted the shuttle averaged only about 300 passengers per hour per direction at the time, so the jump in rail capacity is dramatic. Under the bilateral agreement, KTMB rail services into Singapore will cease within six months of the RTS Link starting passenger service, so the RTS becomes the single cross-border rail option.
Will the RTS Link really ease the Causeway jam?
The RTS Link should take a meaningful slice of peak commuters off buses and the road, especially people who currently walk or ride a bus across the Causeway. It is not designed to replace cars, lorries or motorcycles, so road traffic will remain, but every commuter who switches to rail is one fewer person queuing on the bridge.
Where the relief comes from
- Bus passengers: Many Causeway crossers today take cross-border buses and queue twice, at the Bangunan Sultan Iskandar (BSI) CIQ and at Woodlands. A 5-minute train with one clearance point is a strong alternative.
- Walk-in commuters: People who live or work near Bukit Chagar can walk to the station and avoid the road completely.
- Motorcyclists who switch: Some riders may choose rail if fares and connections at both ends are convenient, though this depends on pricing that is still to be announced.
- Weekend and leisure travellers: Singapore visitors heading to JB City Centre for food and shopping gain a quick, predictable option.
What the RTS will not do on its own
Freight, private cars and many motorcycles will still use the Causeway and the Second Link. That is why the RTS is part of a wider package: Singapore has fully implemented QR code clearance at Woodlands and Tuas since January 2025 (ICA reported about 2,000 more travellers cleared per hour during the March 2025 school holidays compared with 2024), Woodlands Checkpoint is being redeveloped for the long term, and Malaysia is adding buses and a traffic dispersal plan around Bukit Chagar. The honest summary is that the RTS Link is the biggest single upgrade to the crossing in decades, and its effect is strongest for people who can reach a station on foot or by short feeder.
Capacity headroom for future growth
Expected ridership of about 40,000 a day at opening is well below what a 10,000 pphpd line can carry across a full operating day, which leaves room for demand to grow as the Johor–Singapore Special Economic Zone, new homes near the station and better feeder services come on stream. Projections are projections, but the headroom is a positive sign for the line’s long-term usefulness.
What makes the 10,000-per-hour capacity work in practice?
Train capacity is only half the story: the stations, immigration halls and feeder links have to keep pace. Both countries have planned a supporting system around Bukit Chagar so that the trains can actually run full at peak.
Immigration hall throughput
According to MRT Corp, the Bukit Chagar ICQ complex will have 100 e-gate lanes accepting QR codes or passports, 10 security screening lanes, 18 baggage scanners and a dedicated lane for passengers without luggage. Travellers flagged for checks are directed to a secondary counter so the main flow keeps moving. Officials expect clearance to take seconds per person once the system is fully running, a projection that will be tested after opening.
Shared core systems with Singapore’s MRT
The RTS Link uses the same four core systems as Singapore’s Thomson–East Coast Line: trains, signalling, communications and the integrated supervisory control system. Heavy maintenance is handled at the TEL’s Mandai Depot, with a light maintenance facility at Bukit Chagar. Using proven systems helps the line run at high frequency reliably.
Feeder links on the Johor side
- Buses: More than 250 additional buses are expected by 2027 to improve first- and last-mile links, with Malaysia’s Stage Bus Service Transformation 2.0 adding buses serving residential areas around Johor Bahru and Bukit Chagar, timed for the RTS opening.
- Rail interchange: A pedestrian bridge from Bukit Chagar to JB Sentral (about 400 m), and an RM60 million bridge giving KTM Komuter passengers direct access to the RTS station, approved in August 2026 with about 12 months of works.
- Park-and-ride: A 1,500-bay facility at Bukit Chagar, plus 700 RTS-designated bays at Coronation Square.
- Future ART: The planned Johor Autonomous Rapid Transit has a Bukit Chagar stop identified, directly connected to the RTS Link.
Together, these links widen the catchment of the station well beyond walking distance, which supports ridership growth over time.
Who benefits most from RTS Link capacity?
The people who gain most are those who can reach Bukit Chagar station quickly and predictably, because the time saved on the bridge is only valuable if the first and last mile are easy.
- Residents within walking distance of Bukit Chagar: They can walk to the station, clear immigration once, and be in Woodlands North in about five minutes.
- Daily commuters to Singapore’s north: Woodlands North station connects with Singapore’s Thomson–East Coast Line, opening up onward MRT journeys.
- Tenants working in Singapore: A home near the station can be a strong selling point for renters who cross every day.
- Families and visitors: Weekend trips, school runs and family visits become easier to plan when the crossing time is predictable.

What RTS capacity means for homes near Bukit Chagar
A high-capacity, high-frequency line tends to make walking distance to a station more valuable, because residents can rely on it every day rather than occasionally. That is why condos within a short walk of the RTS have drawn so much attention from buyers.
Causewayz Square (Exsim CIQ)
Causewayz Square, often called the Exsim CIQ project and sometimes searched as “Causeway Square JB”, sits on Jalan Lumba Kuda in Tanjung Puteri, about 800 m from the RTS Bukit Chagar station and about 600 m from the JB CIQ. It is freehold, with four towers (Axis, Brixton, Coven and Dover), around 90,000 sq ft of podium retail and a target completion of around 2030. A pedestrian link to the CIQ and RTS has been proposed by the developer. Our walking guide from Causewayz Square to the CIQ and RTS maps the route.
The Asteriaz and The Celestz
EXSIM’s Kebun Teh projects, The Asteriaz and The Celestz, are not within walking distance of the RTS, but the CIQ is about a 10-minute drive away (around 3.2 km), and a shuttle to the CIQ and RTS has been proposed. For residents there, RTS capacity matters as a reliable option at the end of a short drive or ride.
Historically, homes close to new rail stations in many cities have tended to attract stronger tenant demand, although results vary with supply, pricing and the wider market.

Planning your commute around RTS capacity
The best approach is to treat February 2027 as the target, watch for the official timetable and fares, and expect the first few weeks to be a settling-in period.
- Peak times: Trains every 3.6 minutes keep platform waits short, but immigration halls will be busiest at the start and end of the working day.
- Fares: Not announced yet; both governments have said details will come before launch. See our RTS fare guide.
- Getting to the station: More than 250 additional buses are expected by 2027 for first- and last-mile connections, plus park-and-ride bays at Bukit Chagar; see our RTS parking guide.
- Trial and certification: Final system tests and trial runs are expected to finish by 31 December 2026, followed by independent safety certification and regulatory approval.
