1) Buy a round-trip train ticket on the International Express Train to Malaysia.
2) Go to the train station in Butterworth for the return trip to Thailand.
3) Discover the train from Thailand has been cancelled and will not provide the second half of your r/t journey.
4) Have the Malaysian railway staff stamp your ticket as unused from Butterworth to Hat Yai in Thailand so you can receive a refund for whatever portion of it goes to waste.
5) Get a seat in a mini-van that will take you to Hat Yai where you can possibly take your assigned seat on a train that has inexplicably refused to pick you up in Malaysia.
6) Sit tight as the mini-van driver races through Northern Malaysia to get you to Southern Thailand in time to catch the Little Engine that Couldn't (Be Bothered to Complete Its Journey) and ignore the truly spectacular auto accident that you speed past. (How did that car end up in a standing position, anyway?)
7) Take your seat on one of the dirtiest train carriages it has ever been your privilege to ride in.
8) Hold your breath when you have to visit the toilet. Try not to retch as you observe the clogged sink become fuller and fuller with grey, scummy water. Pray that cholera isn't on the rise at this particular point in Thai history.
9) Reach your Bangkok destination an hour behind schedule. Discover that although you spent 400 baht to reach a train that should have come to you, your refund will be 20 baht. Talk to a Thai lady who spent double the amount of your mini-van expenditure on a share-taxi to reach the same train and also received 20 baht. Notice on your train schedule that the cost of a ticket between Butterworth and Hat Yai is 50 baht.
10) Leave your 20 baht refund on the counter staffed by the surliest man in the Kingdom of Thailand. Try not to tell him to buy himself some manners.
11) Find out that your train failed to pick you up because it had "too many delays." Try not to wonder why, even though it left on time from Hat Yai, it was still an hour late in reaching Bangkok.
12) Realize Air Asia, a Malaysian carrier, is a much better bet than the Thai Railway .
13) Understand that for Thai citizens, this lack of consideration on the part of government bureaucracy is a fact of life, although judging by the lady you talked to, it still pisses them off.
14) Hope it pisses them off enough to change it.
15) Congratulate yourself on having an honest-to-god, genuine Thai experience--many farang never attain that privilege.
16) Pray that the motion sickness that was the souvenir of this journey will eventually go away.
