There are several ways to travel from Bangkok to Ubon Ratchathani, but for comfort-seeking travellers, none can match the nostalgic charm and relaxation of the overnight sleeper train. While local buses are a budget option and a domestic flight is fast, they simply cannot replicate the peaceful experience of watching the Thai countryside roll by from your own air-conditioned berth. When you want to enjoy the journey as much as the destination, travel without stress and avoid chaotic airport lines, the train is undoubtedly your top choice.
In This Travel Guide
Why Travelling by Train is Your Best Option to Reach Ubon Ratchathani
1. Traveling at Night Saves You a Hotel Bill
Because the journey to Ubon Ratchathani covers around 600 kilometers, traveling by day means spending almost ten hours watching the clock, which can be a bit boring and feel like a wasted day of your holiday. Choosing the comfort of the night train will solve this for you. You board the train in the evening in Bangkok, enjoy a peaceful night and wake up just as the train arrives at your destination in Ubon Ratchathani the next morning. It’s a highly efficient way to travel and saves you a hotel bill at the same time.
2. Proper Bed and Space to Move Around
Everyone knows buses and airplanes usually offer very little room to move your legs. There is nothing like that on the sleeper train; you will surely enjoy a wonderful sense of freedom and privacy. You can stretch your legs and walk through the carriages whenever you please. You will receive freshly laundered bedsheets, a clean pillow and a warm blanket. Whether you choose to sleep right away or simply lie down and enjoy the gentle rhythm of the tracks is completely up to you.
3. Reliable, Safe and Smooth Journey
Safety and peace of mind matter for most travelers. Luckily, Thailand’s overnight trains are reliable and safe. The staff members on board are very welcoming and the modern night trains offer a very smooth ride compared to the often bumpy and stressful Thai highways. It will allow you to travel with peace of mind.
4. Scenic and Authentic Window into Rural Thailand
The best moment is when you wake up and see the sunrise from the comfort of your train window with a cup of coffee. You will look out over peaceful green rice fields, traditional villages and water buffaloes roaming the countryside. It’s a slow-paced and beautiful introduction to the Isan area that you would completely miss from the window of an airplane.
5. Classic travel experience
Other than that, it will offer you a nostalgic traveling experience. There is something different about traveling by train, especially at nighttime. On the train, you will mostly find a pleasant mix of friendly locals returning home and maybe some like-minded international travelers. Traveling by train will provide you with a more authentic glimpse into daily Thai life, making your trip to Ubon Ratchathani feel like a memorable experience rather than just the next transit from point A to B.
Choosing the Right Train for You
When looking at the timetable for trains from Bangkok to Ubon Ratchathani, you will notice different types of trains: Rapid, Express and Special Express. If you value a good night’s sleep, modern comfort and don’t want to stop at every station along the way, the choice is simple. You will want to avoid the older Rapid trains, which often only have fans and hard seats, and you can also forget about the slower Express services.
Therefore, we will focus on the Special Express services, which leaves us with two options: Special Express No. 23 and Special Express No. 139.
Special Express No. 23
If you are looking for the absolute highest level of comfort, you should book Special Express Train No. 23. This is one of Thailand’s ultra-modern trains; they look sleek and run incredibly smoothly. Inside you can enjoy the following features: clean, vacuum-style toilets (similar to airplanes), personal reading lights, USB charging ports at every bed and even an LCD screen showing the journey’s progress. It actually feels more like a modern hotel on wheels than a traditional train.
The only thing left for you to do is choose between 1st and 2nd class, but no worries, we will help you with that as well.
1st Class Sleeper (Air-Conditioned Private Cabin)
For the ultimate comfort and privacy, the 1st Class sleeper on Train No. 23 will be your choice. You get a private, lockable cabin for two people, featuring a washbasin with a mirror right inside your room so you don’t need to leave your cabin to wash your hands or brush your teeth. The beds are remarkably comfortable, and the air conditioning can be adjusted individually in your cabin. Your luggage can easily be stored underneath the lower bed.
Important tip so you don’t miss out: these tickets sell out very quickly, so ideally you want to book 30 days ahead of time.
2nd Class Sleeper (Air-Conditioned Open Carriage)
If you didn’t have the time to book early and 1st class is sold out, the 2nd Class sleeper on Train No. 23 is still a good and comfortable choice. Instead of private cabins, this is an open-plan carriage with wide, comfortable seats that face each other during the day. In the evening, these seats turn into upper and lower berths. High-quality curtains block out the light from the corridor, creating a cozy and private sleeping pod.
Important tip for comfort: Always book the Lower Berth (the bottom bed). The lower bed is slightly wider than the top one, has a proper window to look outside and you don’t have to climb a small ladder to get into bed.
Special Express No. 139
If Train No. 23 does not fit your schedule or is fully booked, Special Express No. 139 is your next best option. This train uses slightly older, classic purple carriage models. While it doesn’t have the modern touchscreens or USB ports, the 1st and 2nd class air-conditioned sleepers are still clean, very spacious and well-maintained. It offers a slightly more nostalgic, old-school train experience without sacrificing the comfort of a flat bed and cool air conditioning.
How to Navigate Bangkok’s Krung Thep Aphiwat Central Terminal
For decades, train journeys in Bangkok started from the charming but chaotic and hot Hua Lamphong Station. However, times have changed. Today, all long-distance trains to Ubon Ratchathani depart from Bangkok’s hyper-modern rail hub: Krung Thep Aphiwat Central Terminal, also known to locals and taxi drivers as Bang Sue Grand Station. Quick Thai language lesson: Krung Thep is how Thai people call Bangkok.
The new train terminal is massive and navigating it can sometimes feel a bit overwhelming, especially when it’s your first time. Here is exactly what to expect and how to ensure a smooth, relaxed start to your rail adventure.
Getting to the Station with Ease
The easiest and most comfortable way to reach the station with your luggage is by taking a Grab taxi directly from your hotel. Simply type in “Krung Thep Aphiwat Central Terminal” as your destination. The driver will drop you off right at the main entrance.
If you prefer public transportation, the station is directly connected to the MRT Blue Line (Bang Sue Station). From the underground metro station, you can follow the clear, air-conditioned underground walkways and escalators straight into the main departure hall.
A Modern Airport-Style Terminal
When you step inside, you will notice that this terminal looks and feels more like a modern international airport than a traditional Asian train station. It’s fully air-conditioned, clean, well-lit and very spacious. And although it’s big, it’s easy to find your way.
Finding your train: Simply look at the large digital departure screens (available in English) to find your train number (e.g., Special Express No. 23). The screen will show you which Gate and Platform you need.
Ticket Check: Long-distance departures, like your trip to Ubon Ratchathani, are organized through specific boarding gates. Just have your printed ticket or your smartphone ticket ready to show the staff at the gate and you will be completely fine.
Where to Wait and Have a Bite to Eat
We highly recommend arriving at the station at least 45 to 60 minutes before departure. The seating areas near the check-in gates are comfortable and being early gives you plenty of time to relax and find your way without rushing. The air-conditioned waiting rooms can be a bit cold at times, so it could be a good idea to bring a sweater.
If you feel hungry and want to grab a bite to eat or buy some refreshments for the journey, head to the food court area. It is the perfect spot to buy a bottle of water and some light snacks for your journey on the train. Here you will find a variety of clean food stalls, coffee shops and convenience stores like 7-Eleven.
Boarding the Train
Unlike older stations where you had to walk across the tracks, Krung Thep Aphiwat uses clean, modern platforms accessible via escalators and lifts. When your gate opens, staff will guide you up to the platform. Friendly train attendants will be waiting at the door of your carriage to check your ticket one last time and point you toward your comfortable seat. Their service is great and there really is nothing to worry about.
Booking Your Train Tickets Safely and Without Hassle
The Special Express trains are popular, especially the 1st Class private cabins and 2nd Class lower berths. So if you don’t want to miss out on these, booking in advance is highly recommended. In our experience, Train No. 23 often opens for reservations 30 to 90 days before the departure date. Booking at least 30 days in advance should be safe enough to get yourself into that preferred and comfortable 1st Class cabin we were talking about earlier. But, if you want to be completely safe, book your ticket as soon as possible, especially during busy periods like the famous Candle Festival in Ubon Ratchathani.
As for the booking process, here are the best and safest ways to secure your train tickets online before your trip.
1. Using a Trusted Booking Partner (Recommended for Convenience)
If you prefer a smooth, hassle-free booking experience, we highly recommend using a dedicated travel platform. There are two major, trusted booking partners in Southeast Asia that specialize in Thai train tickets:
12Go.asia: If you prefer a smooth, hassle-free booking experience, we highly recommend using a dedicated travel platform. There are two major, trusted booking partners in Southeast Asia that specialize in Thai train tickets. The most widely used transportation platform in Thailand is 12Go.asia, which shows all available trains, classes and live prices in a clear overview. Their system is highly reliable and accepts international payment methods like Visa, Mastercard or PayPal.
Baolau: A great alternative that has become popular among independent travellers is Baolau. It offers a very clean interface that easily connects you to the official State Railway system, displays all classes clearly, sends your electronic tickets directly via email and provides excellent multilingual customer support.
Both platforms charge a small but reasonable service fee. The peace of mind, secure payment and ease of use are well worth it. You can simply show your electronic ticket on your smartphone when boarding.
2. D-Ticket (The Official State Railway Website)
The official booking platform run by the State Railway of Thailand (SRT) is called D-Ticket. You can find their official website online or download the D-Ticket app on your smartphone. While you pay the exact official ticket price here, the system is notorious for rejecting international credit cards. For a stress-free experience, using a trusted partner like 12Go.asia or Baolau is highly recommended.
Important Tips for a Successful Booking
Mark your calendar: Book your tickets 30 to 90 days before your journey to get the best possible seats you can get.
Double-check the stations: Make sure your departure station is listed as Krung Thep Aphiwat Central Terminal (and not the old Hua Lamphong).
Choose the right berth: If you are booking 2nd Class, look closely at the description and ensure you select the Lower Berth for maximum space and comfort.
5 Essential Tips for a Comfortable Night on the Train
An overnight train journey through Thailand is a wonderful adventure, but a few small preparations can make the difference between a restless night and a deeply relaxing trip. Because your comfort is our top priority, we have gathered five essential insider tips to help you get the most out of your night on the rails to Ubon Ratchathani.
1. The Air-Con Challenge
If there is one thing Thai trains are famous for, it is their incredibly powerful air conditioning. The carriages are often kept very cool throughout the night. While the train attendants provide a clean, warm blanket, it is highly recommended to dress in layers. Pack a comfortable sweatshirt, long trousers and a pair of warm socks in your hand luggage. This ensures you can adjust your temperature easily and stay cozy all night long.
2. Choose the Lower Berth for Extra Space and a Window
When booking a 2nd Class sleeper carriage, you will have the choice between an upper and a lower berth. Here is why you should always take the lower berth:
Accessibility: You don’t want to climb up and down a narrow ladder or, even worse, fall out of bed while sleeping. You wouldn’t be the first one.
Space: The lower beds are significantly wider than the upper ones, giving you plenty of room to turn around without hitting the wall with your knees and elbows.
The View: The lower berth has its own large window. The best part of your trip will be sliding your curtain open in the morning and watching the rural Thai sunrise from your own bed.
3. Bring Your Own Favorite Snacks and Drinks
While the modern Special Express trains (like No. 23) often have a canteen or food car on board, the selection can be somewhat limited and basic. To ensure you have exactly what you like, stop by a convenience store at Krung Thep Aphiwat station before boarding. Bring some fresh fruit, a few pastries, a bottle of water or your favorite snacks.
Note: Alcohol is strictly prohibited on Thai trains or at stations, so keep it to soft drinks or tea.
4. Pack a Small Overnight Bag
Your large suitcases will be safely stored under or near your seat, but you don’t want to be rummaging through them in the middle of the night. Pack a small, accessible bag with your nighttime essentials: a toothbrush, toothpaste, wet wipes and any personal medications. Having these items close at hand makes getting ready for bed or refreshing yourself in the morning a breeze. We always add some fresh clothes for the next day as well.
5. Bring Earplugs and an Eye Mask
The modern CNR trains are remarkably quiet and smooth compared to older models, but it remains a moving train. You will occasionally hear the gentle hum of the tracks or the soft sound of a door opening. Carriages also keep some safety lights on during the night. If you are a light sleeper like us, a simple pair of earplugs and a comfortable eye mask will allow you to drift off into a good night’s sleep.
Arriving at Ubon Ratchathani Station: What’s Next?
As the soft morning light fills your carriage and the train gently slows down, you will know you have arrived in the peaceful northeast. After an 8 to 11-hour journey, the train pulls into its final stop: Ubon Ratchathani Railway Station.
Arriving in a new city early in the morning can be very exciting but also bring some logistical questions. Here is exactly what you need to know to make your arrival and transit to your hotel completely seamless.
A Quick Geography Note: Where Are You?
The first thing that is helpful to know is that Ubon Ratchathani Station is actually located in Warin Chamrap, a lively town just south of the Mun River. The actual city center of Ubon Ratchathani, where most of the hotels, temples and restaurants are located, lies about 3 to 5 kilometers north across the river. You will need a short ride to get to your final destination.
The Best Ways to Reach Your Hotel
When you step off the train and exit the station, you will be greeted by several local transport options. We will list the two best options for you based on comfort and a fair price.
Grab Car – The Most Comfortable Option
This is your best option. Just like in Bangkok, the Grab app works exceptionally well in Ubon Ratchathani. As soon as you get off the train, open the app, enter your hotel name and request a car. A clean, air-conditioned private car will pick you up right outside the station. The price is fixed beforehand in the app, you can pay safely via your linked credit card and off you go.
Local Taxi Meter – The Reliable Alternative
If you don’t have your Grab app installed, no worries. Directly outside the station exit, you will find a dedicated taxi stand with official, air-conditioned car taxis. These taxis operate on a meter, though they sometimes charge a small flat airport/station surcharge. They are a reliable and comfortable alternative to the Grab app. Make sure the driver turns on the meter before you depart.
Storing Your Luggage and Starting Your First Day
Because overnight trains usually arrive early in the morning (often between 6:00 AM and 8:00 AM), it is highly likely your hotel room will not be ready for check-in yet. Don’t worry! Simply head straight to your hotel anyway. Almost all hotels in Ubon Ratchathani will happily store your luggage for free.
Once your bags are safely tucked away, you can head out into the fresh morning air, find a lovely local café for a fresh coffee and a traditional Thai breakfast, and begin exploring this beautifully authentic, untouristed corner of Thailand at your own relaxed pace.
Recommended Places to Stay in Ubon Ratchathani
To make your arrival even more comfortable, we highly recommend staying at a hotel that offers excellent service, comfortable amenities and a welcoming atmosphere for early arrivals. Here are our top recommendations:
Yuu Hotel Ubon Ratchathani: Located right in the cultural heart of the city, it is just a short walk from the local night market and the Thung Si Mueang city park. The welcoming staff, on-site café and its beautiful French-colonial design make it the perfect place to unwind after your train journey. We actually had our wedding here, and the staff and atmosphere of the location truly made it the best day of our life.
You can check availability and book Yuu Hotel on Booking.com or Agoda.
Centara Ubon: If you prefer a more modern, international upscale experience, we recommend you this hotel. Located just outside of the city and right next to the Central Ubon shopping mall, The hotel offers maximum convenience with spacious, quiet rooms, a outdoor swimming pool and a top-tier breakfast buffet. It provides the perfect blend of luxury and Isan hospitality. In the Central Ubon shopping mall, you will find lots of Thai and Western restaurants and a Tops supermarket with products from all over the world if you want to grab a familiar snack from your own country.
You can check availability and book Centara Ubon on Booking.com or Agoda.
Final Thoughts on Your Journey to Ubon Ratchathani
Taking the train from Bangkok to Ubon Ratchathani is far more than just a way to travel between two cities. It is a wonderful introduction to the slower, more authentic pace of northeastern Thailand. As the urban landscape of the capital fades into the scenic countryside and rolling fields of Isan, you will truly feel your adventure begin.
