Bangkok's rail network is the backbone of the city's transportation system. With over 90 stations across multiple lines, the BTS Skytrain and MRT subway systems offer fast, affordable, and air-conditioned travel throughout the sprawling metropolis. For expats, mastering these systems is essential for daily commuting and exploring the city.

Rush Hour Survival Guide
Bangkok rush hours are intense. The trains get extremely crowded, especially at major interchange stations. Here's how to manage:
Peak Hours
- Morning Rush: 7:30 AM - 9:00 AM
- Evening Rush: 5:30 PM - 7:30 PM
- Busiest Stations: Siam, Asok/Sukhumvit, Mo Chit, Phaya Thai
- Most Crowded Lines: BTS Sukhumvit Line, MRT Blue Line central section
Tips for Rush Hour
- Leave Earlier or Later: Traveling before 7:30 AM or after 9:30 AM makes a huge difference. Same for evenings.
- Position Yourself Strategically: Stand where doors will open (marked on platform) and near the front or back of the train where it's less crowded.
- Have Your Card Ready: Don't fumble at the gates. Hold your Rabbit or MRT card in hand before reaching the turnstile.
- Use Less Crowded Cars: The first and last cars are usually slightly less packed than middle cars.
- Consider Alternative Routes: Sometimes a longer route with fewer transfers is faster during rush hour.
- Women's Cars: Some trains have women-only cars during rush hour (marked with pink signs). Men should avoid these cars.
- Keep Bags Small: Large backpacks make crowded trains worse for everyone. Consider a smaller bag for commuting.
Avoid at All Costs
Siam station at 6:00 PM on a Friday is absolute chaos. If possible, walk to National Stadium or Chit Lom instead. The interchange between BTS and MRT at Asok/Sukhumvit is similarly packed during rush hour.
Practical Tips for Daily Riders
Etiquette
- Let passengers exit before boarding
- Move to the center of the car, don't block doors
- Remove backpacks in crowded trains
- Keep phone conversations brief and quiet
- Offer seats to elderly, pregnant, and monks
- No eating or drinking on trains (it's prohibited)
Useful Apps
- BKK Rail: Offline map, fare calculator, route planner
- Google Maps: Real-time transit directions including rail
- ViaBus: For connecting bus routes
- Rabbit LINE Pay: Digital Rabbit card and payments
Accessibility
All BTS and MRT stations have elevators and accessibility features. Station staff are generally helpful with wheelchairs and mobility needs. Some older BTS stations have only escalators to street level, but staff can assist with alternative routes.
Safety
- Stations are well-staffed and have security cameras
- Petty theft is rare but keep valuables secure during crowded times
- Emergency intercoms are available on platforms
- Yellow safety lines on platforms - stay behind them
