Here's a KTX train ticket. It's about the size of a credit card.
I went to Busan last weekend to attend a family gathering, and it cost me a lot of money, but still, I could it was cheap when I consider the amount of time that was saved thanks to the fast train (Korea Train eXpress - KTX) .
If you're thinking of going from Seoul to Busan or the other way around, taking the KTX is the fastest, and you can buy a ticket very easily from any automatic ticket vending machine at Seoul Station (although Busan station doesn't have automatic ticket machines yet and you have to go to the ticket windows.)
good to know. oh how i wanna visit korea...so expensive lol...maybe i'll write a letter to my mom's sister and ask her to send me a ticket lol j/k i wouldn't do that. hopefully next year tho i'll be able to make the trip. with the cost of stuff in the USA going up it's getting hard to afford gas for my car.
Last time we were there trains ran really frequently but some were hard to get on, particularly end of the day and weekends. I'd suggest getting your ticket early if a specific travel time is critical.
