Back when I lived on Line 9, a handful of stops from GMP, I always took the train to ICN. Taking the commuter to GMP and then crossing the platform to an express line 9 train was nearly always quicker than the bus, and at least 50% the price. The train can be the better option in select cases, but most parts of Seoul are best served by the busses.
