BUSAN (Yonhap News) ― Forty passengers were taken to area hospitals for minor injuries Monday after a running subway train caught fire in the southern port city of Busan, fire authorities said.

The blaze broke out around 2:06 p.m. when electric sparks ignited a fire on one of the power suppliers of the northbound subway train heading toward Daeti Station on line No. 1, the authorities said.

“Sparks were flying from the exterior part when the train was about 200 meters away from the station,” a railroad engineer was quoted by the fire authorities as saying. “Passengers were evacuated as soon as the train arrived at the platform.”

Of some 100 passengers on the train, 40 were taken to nearby hospitals for minor smoke inhalation, including a 25-year-old passenger who reportedly had his bronchial tubes damaged due to inhaling smoke.
