TAIPEI, Taiwan — The conductor of a train that crashed in northern Taiwan, killing 18 people, had reported problems with the power system multiple times before the accident, the local news media said Monday.

Among the dead in the Sunday afternoon crash were eight members of a family returning from a wedding, Taiwan’s railway authority confirmed. An additional 190 people were injured in the island’s worst such accident in 37 years.

On Monday morning, the Taiwan Railways Administration released a 12-second video of the moment the Puyuma Express train derailed in northeast Taiwan’s Yilan County. The train was carrying 366 passengers.
