Kuala Lumpur’s trains are driverless, air-conditioned, and cheap — a handful of ringgit gets you most places, and everything runs on one card. The catch for a first-timer is that it’s several rail networks under one roof rather than a single system, so knowing which line does what makes the city click into place.
The basics
The backbone is RapidKL, run by Prasarana, which operates a web of driverless rail:
- LRT — three lines (Kelana Jaya, Ampang, Sri Petaling) plus the newer Shah Alam Line, covering the older, denser parts of the network.
- MRT — two lines (Kajang and Putrajaya), the newest and longest-reaching rail, connecting the southern and eastern suburbs.
- KL Monorail — a single elevated loop through the tourist core (KL Sentral, Bukit Bintang, Titiwangsa).
- BRT Sunway Line — a dedicated busway serving Sunway and Subang Jaya.
- RapidKL buses — city and feeder routes filling in the gaps between rail lines.
Two more systems run alongside RapidKL: KTM Komuter, a commuter rail line through KL Sentral useful for reaching Batu Caves, and the Express Rail Link (ERL), which runs the airport trains (KLIA Ekspres and KLIA Transit) between KL Sentral and KLIA.
How to pay
Everything runs on Touch ‘n Go, Malaysia’s tap-card system:
- Buy a Touch ‘n Go card (RM10) at any RapidKL station counter, the Touch ‘n Go Shop at Nu Sentral next to KL Sentral, convenience stores, or kiosks at the airport. Load it with credit at a station machine, a convenience store, or through the Touch ‘n Go eWallet app.
- Tap in and out every time — unlike a flat-fare system, RapidKL rail charges by distance, so you tap the card reader entering and leaving the paid area. Forgetting to tap out on exit can charge you the maximum fare.
- Buses are cashless-only — tap your Touch ‘n Go card on the reader by the driver; there’s no paying with cash.
- Single-journey tokens are sold at station machines if you don’t want a card, but they cost more than tapping Touch ‘n Go and only work for that one trip.
There’s no tapping a foreign contactless bank card or phone at the gates — Touch ‘n Go (card or token) is the only way in.
Fares
RapidKL’s LRT, MRT, Monorail, and BRT all price by distance, cheaper with Touch ‘n Go than with a token:
| Touch ‘n Go | Cash / token | |
|---|---|---|
| Shortest ride | ~RM1.00 | ~RM1.00 |
| Longest cross-network ride | ~RM6.70 | ~RM7.90 |
RapidKL buses are also zone-based: RM1.00 to RM5.00 per ride for adults (RM0.50–RM2.50 for concession-card holders), Touch ‘n Go only.
If you’re staying a while, the Rapid Bulanan Pass (RM150) covers unlimited rides on all RapidKL rail and bus services for 30 days and is open to everyone, tourists included. RapidKL also sells a cheaper unlimited pass, My50 (RM50/30 days), but it’s restricted to Malaysians with a MyKad or MyTentera.
Getting from the airport
The fastest way into the city is KLIA Ekspres, a nonstop train straight to KL Sentral:
- Time: about 28 minutes to KLIA Terminal 1 (add roughly 3 minutes for Terminal 2).
- Cost: RM55 one-way (RM100 return).
- How often: every 20 minutes, all day, every day, including public holidays.
- Hours: first trains leave KL Sentral around 5:00am and KLIA around 4:55am; regular nonstop service runs until around midnight, and from 11pm trains switch to making all stops, extending service from KLIA T1 and T2 until about 1:00am.
The same operator runs KLIA Transit, a slower train on the same tracks that also stops at Bandar Tasik Selatan and Putrajaya & Cyberjaya — useful if you’re headed to Putrajaya rather than downtown KL, and cheaper for those shorter hops (RM6.50 to Bandar Tasik Selatan, RM14 to Putrajaya & Cyberjaya).
If you’re combining the airport transfer with a few days of city travel, the KL TravelPass bundles a KLIA Ekspres ride with two consecutive days of unlimited RapidKL rail and bus rides on one card.
Apps to download
- MyRapid PULSE — RapidKL’s own app for trip planning, real-time bus arrivals, and service alerts.
- Touch ‘n Go eWallet — reload your card, buy passes, and manage your balance from your phone.
- Google Maps — solid for trip planning with live RapidKL data.
- Grab — the region’s ride-hailing app, handy for last-mile trips or once the trains stop for the night.
When it runs
RapidKL rail and buses run daily from around 6:00am to just before midnight. Peak frequency is strong — the Kelana Jaya and Kajang lines run about every 4 minutes, Ampang/Sri Petaling about every 5 minutes — while in-town buses run about every 15–20 minutes even at peak, thinning out further off-peak. There’s no true overnight service, so plan your last ride before midnight or budget for a Grab.
Accessibility
RapidKL offers Rapid Mobility, a door-to-door van service with a hydraulic wheelchair lift for riders who can’t use standard trains or buses — it takes up to 3 wheelchairs per van in the Klang Valley, costs RM7 per trip, and needs booking at least 3 working days ahead. Riders with disabilities and their caregivers get priority boarding on any coach, and concession cards give a 50% fare discount to eligible riders.
Etiquette & local quirks
- Tap in, tap out — always. Since fares are distance-based, skipping the exit tap can cost you the network’s maximum fare.
- Look for the Women Only Coach (Koc Wanita) on the MRT Kajang and Putrajaya lines — it’s in the middle of the train (around the second and third cars), marked with pink stickers, and open to women of any age plus boys 12 and under with a female guardian.
- Escalator etiquette is taken seriously: stand on the left, walk on the right.
- Trains and stations are air-conditioned — bring a layer if you run cold.
Good to know
- Fare gates, not honor system. Unlike some cities, RapidKL stations are fully gated — you can’t board without tapping in.
- Cash doesn’t work on trains. Stations sell tokens from machines, but you’ll want a Touch ‘n Go card for anything beyond a single ride.
- Rain happens fast. Kuala Lumpur gets sudden, heavy downpours year-round — covered walkways link many stations to nearby malls, but keep an umbrella handy.
