A rail map showed a line from Andong (안동) to Jeonju (전주). But Google Maps says I have to go transfer twice on a much longer route. Korail schedule search says there are no direct trains and transfer routes are not possible. I presume the difference in wording between the two is significant but I don't know what it means.
Bus is more direct and faster (four+ hours vs. six+), but I already have a flexible four-day Korail pass paid for (with one day already used).
