High Speed Metro is a new trend in South Korea. Though its capital city of Seoul has been devoted to building subway lines or supplemental Light Rail system, most of the city is now covered by rail networks. So, it's time to extend railways toward outer side of Seoul. But, longer travel time would deteriorate the demand of building new houses.
Then, High Speed Metro was invented. I thought that express trains on conventional lines would play the similar role. But, they might have been insufficient.
