Does the train go to Seoul now? Last time I was there it only went to Gimpo airport (which took 28 minutes, not any more "high speed" than taking the bus). Gimpo is only about halfway to Seoul. It is supposed to open all the way this year, but I googled this and didn't find anything that said it had opened yet.
