On July 15, 2011, 150 passengers were evacuated from a train when smoke started coming out of the train when it arrived at Miryang Station at 11:30 AM. On July 17, 2011 at around 11 AM, a train stopped abruptly and stranded some 400 passengers in the Hwanghak Tunnel for over an hour. The train resumed service after emergency repairs to a malfunctioning motor. A Korail spokesperson stated that the reason for the stop was due to "faults in the motor block that supplies power to the wheels". The same day, the air conditioning broke down on another train leaving Busan at 1:45 PM. Over 800 passengers were transferred to another train at Daejeon when the problem could not be fixed.
