31 trains a day cross the causeway by rail instead of road — here's the full schedule, and why booking early matters more than picking a good time.
The KTM Shuttle Tebrau is the one crossing where the actual border-crossing part takes less time than getting to the platform — the train ride itself covers the causeway in about five minutes. Almost everything people struggle with here is the queue on either side of it, not the ride.

Source: Causeway Kaki's own tracked shuttle timetable (confirmed 27 July 2026), cross-checked against KTMB's published booking-site schedule as independently republished in August 2026. The extra five JB-side departures aren't a typo — more Johor residents ride into Singapore for work than the reverse, and the timetable reflects that.
Tickets open on KTMB's booking site about a month ahead, capped at 6 per transaction online (4 at the counter), and weekend or holiday slots — especially the early-morning JB-to-Singapore departures — routinely sell out days in advance. Same-day tickets during peak hours are close to a lottery. Budget 40–50 minutes before departure to clear immigration; gates close 20 minutes before the train leaves.
One thing worth knowing before you build a routine around this: the service has a stated shelf life. KTMB's shuttle is expected to keep running only until roughly six months after the RTS Link — the new direct rail crossing — opens, itself targeted for around the turn of 2026 into 2027. Treat it as a crossing with an end date, not a permanent fixture.
Sold out doesn't mean gone — KTMB releases extra slots when it can, and they don't stay open long. Causeway Kaki watches for those releases and surfaces them as soon as they appear, so you're not the one refreshing the booking site every few minutes.
