A passenger train travelling near the city of Tacoma in Washington state in the United States, derailed on Monday killing at least three people and injuring more than 100.
The train was making its maiden voyage along a faster route when it hurtled off an overpass onto a busy highway.
Although it is expected to take months of investigation to determine the exact cause of the crash, it is believed that the train hit something on the track around 64 kilometres south of Seattle, before derailing. Speed is also believed to be a factor.
According to transitdocs.com, a site which maps train speeds using data from Amtrak’s train tracker app, the train was travelling at 130.5km per hour before it derailed.
The maximum speed for passenger trains just before the tracks curve to cross Interstate 5 drops from 127km per hour to 48km per hour, a track chart prepared by the Washington State Department of Transportation stipulates.
Around 13 train cars jumped the tracks, which set off a chain reaction crash which involved several motor vehicles on the road below.
