Fortunately, nobody appears to have suffered serious injury following the accident which happened on Friday after one train ran into the back of another that had stopped at a station.

The accident was reportedly caused by a signal failure. The two subway cars were derailed.

Last month, a ferry carrying mainly school students capsized off the South Korean coast, leaving more than 300 people dead or missing, and South Koreans have criticized the government for lax safety practices.
