In many destinations, train stations are located very centrally and have good transport connections with the rest of the city, bus stations, and airports. It mostly concerns the older and well-established railway stations. The newer and bigger ones tend to appear in the outskirts of towns and cities, first of all, due to the reason of limited space in the central locations. Getting to and from there may be challenging even by taxi, as restrictions may apply on taxi operators allowed to serve the passengers. Hence, we highly recommend double-checking the location of the station you will depart from and arrive at as some destinations have several train stations.

There may be carriages of a different class on one and the same train on one and the same route. The price of your ticket will vary accordingly – from a dirt-cheap tag for hard seats to high numbers for super comfy overnight sleeper berths on luxury trains. For the Bangkok – Udon Thani route, the cheapest ticket costs while if you want to travel with more comfort, expect to pay for the most expensive option.

• Train tickets often sell out well before the date of departure. Book them in advance even if your travel does not fall onto high-season dates. Travelling during peak periods which also include public and national holidays, and long or bank weekends, advanced booking is a must if you do not want to remake your travel plans on the spot. It is unnecessary to go to the train station to book – buy your ticket online in a few clicks.
• Advanced booking ensures you get the seats and berths you want. For example, the lower berths are always the first to sell out, while upper berths may be available even on the departure date. Similarly, for longer distances, it is the night trips that enjoy the highest demand, while you may be able to grab a ticket for the same route an hour before departure if it is an inconvenient day ride that eats a huge part of your time.
• There may be different carriages within one and the same train: fan-only and air-conditioned; hard seats and soft seats; second class berths and private compartments. Before buying your ticket, make sure you understand what type of seat you are paying for. Prices may differ greatly, but sometimes it is a good idea to pay more not to spend 20 hours on a hard seat in a fan-only carriage. In general, second-class berths are a good choice for longer overnight trips, while for shorter 4-6-hour day journeys, a soft seat is a great option.
• Air-conditioning on trains can be excessive – as well as heating during the cold season. Make sure to pack layers not to get cold or hot during your trip. In hot countries, fan-only carriages are a cheaper and acceptable alternative to air-conditioned carriages.
• There are toilets on board a train. Depending on the type of train, some carriages can be equipped with simple squat-type toilets or normal Western toilets. Regardless of your ticket's price, the train toilets' cleanness is not often up to the standard, alas. It especially concerns cheaper classes, though even in first-class carriages, complaints are not unheard of.
• There is normally a dining carriage on long-distance trains, but on some routes, dining carriages have become extinct due to covid-19 restrictions. Check in advance if food is available on board or simply pack some snacks to be on the safe side. On many trains, you will also see hawkers patrolling the aisles during the journey and selling soft beverages and snacks. Alcohol drinks are prohibited on trains.
• Smoking is prohibited, too, if, of course, you are not travelling by a common class somewhere in China or Indonesia!
• Arrive at the train station at least half an hour before departure to allow enough time to find your platform and go through check-in formalities. A passport or other ID which you use for buying your train ticket is almost always needed, so keep it at hand to produce when asked at check-in or boarding.
• Trains may arrive at their destination later than scheduled. These delays are not uncommon, especially for long-haul routes. Be ready and plan accordingly. Yet compared to buses, trains are less weather and traffic dependent hence more reliable schedule-wise.
