BTS vs MRT: A Beginner’s Guide to Bangkok’s Train Systems and How to Use Them

Getting around Bangkok can be overwhelming for first-time visitors. The traffic is notorious, and figuring out taxis or buses may not always be practical. That’s where Bangkok’s train systems—BTS (Skytrain) and MRT (subway)—come in. Clean, affordable, and efficient, they are must-use tools for anyone exploring the Thai capital.

In this guide, we’ll break down the differences between BTS and MRT, explain how to use them, cover routes and fares, and offer tips to help you travel like a local.

1. What Are BTS and MRT?

  • BTS (Bangkok Mass Transit System)
    Commonly called the Skytrain, BTS is an elevated rail system running through Bangkok’s central business and shopping areas.
  • MRT (Metropolitan Rapid Transit)
    MRT is Bangkok’s subway system, reaching beyond the city center into more local, government, and residential zones.

2. Route Overview and Key Areas

  • BTS Sukhumvit Line (Green): Siam, Asok, Phrom Phong, On Nut
  • BTS Silom Line (Dark Green): Silom, National Stadium, Saphan Taksin
  • MRT Blue Line: Chatuchak, Sukhumvit, Hua Lamphong (main train station)
  • Other MRT lines (Yellow, Purple): Mostly serve outer Bangkok areas

Use Google Maps or the official apps to check which line is best for your route.

3. Fare Structure and Payment Methods

  • BTS fare: 16–59 THB (based on distance)
  • MRT fare: 17–43 THB

Payment options include:

  • Coins or bills at ticket machines
  • Smart cards (stored-value)
  • QR code or contactless credit card at some stations

Note: BTS and MRT use separate card systems—they are not interchangeable.

4. How to Buy Tickets and Use Smart Cards

Buying Single Tickets

  • Use ticket machines by selecting your destination
  • Some machines only accept coins (especially on MRT)
  • You’ll receive a plastic token (MRT) or paper card (BTS)

Using Smart Cards

  • Rabbit Card (BTS): Great for frequent travelers, avoids queueing
  • MRT Card: Similar in function but works only on MRT
  • Available at station counters with initial top-up required

Bonus tip: Tourist day-passes are sometimes available at major BTS stations.

5. Transferring Between BTS and MRT

The most common interchange is:

  • BTS Asok Station ↔ MRT Sukhumvit Station

These are connected via an underground passage.
Note: You’ll exit one system and enter the other, and pay again as they’re separate operators.

Pro tip: Plan routes ahead and allow time for transfers.
