I used to take the train to Buriram to visit my girlfriend. The overnight trains were such a blast. Cheap and easy.
You could stock up on Leo beer and before you got out of Bangkok be pissed and ready to test out the sleeper beds with the random bargirls who happened to be on the train going home to finish the rice harvest. Back then they actually went home to tam na - make rice.
Now they go home to co-sign for a new motorcycle for their Thai boyfriend while Gunther in Munich gets another Western Union ready. Either way - Rail Time as we called it was generally 500 baht and the girls always had their own condoms.
