Seoul City is studying the feasibility of running the subway around the clock.

According to reports, Seoul Metro, which operates subway lines 1-8, is now recruiting experts to conduct the study. It will measure demand for subway services late at night and the cost. The study will be finalized by the end of the year and the company will make its decision early next year.

Seoul's subway lines normally stop operating around 1 a.m. and are back in service from about 5 a.m.
