Chances are, if you are taking a day trip from Bangkok by train, such as to Ayutthaya, you will be using the Hua Lamphong Train Station.
First, take the MRT to the Hua Lamphong stop. Here is a quick explanation of the Bangkok metro system. The Hua Lamphong MRT station exits onto the train station of the same name.
Only a few steps from the MRT and you can be in line to purchase a train ticket. Don’t fear – the signs are in English, as well as Thai, and the staff at the window speak enough English for you to conduct a transaction.
A quick word about the trains – only first class has air conditioning. Second and Third Class have fans only. Third Class seats, although extremely cheap, do not have reserve seats so you might have to stand for your journey if the train is full.
3rd class only trains also don’t have dining cars, but they do have vendors that periodically stroll the aisles selling cold drinks, fruit, and even meals – typical street food fare.
There are also restrooms at the end of each car.
The Hua Lamphong train station is equipped with restrooms, even showers, luggage storage, a book store and other souvenir shops.
After my return trip to Ayutthaya, I decided to explore the train station a little bit more and found a group of eateries next to the waiting area. You first buy a coupon at the front area and then pick your food cafeteria style. This was a quick, inexpensive and delicious meal before heading back to my hotel.
