In the midst of a pouring rain, the staffs of the Korean National Railroad are restoring the warped railway of the Central Railroad on the Wang-Sook River Bridge yesterday afternoon. The pier of the Wang-Sook River Bridge has sunk 20-30 centimeters due to a localized torrential downpour, so that the both-way trains between the Mang-Woo Station and the Do-Nong Station were discontinued entirely.
