On the morning of Dec. 18, tragedy struck the small town of Dupont, Wash., as an Amtrak passenger train derailed, resulting in multiple casualties.

Going over an interstate overpass, the Amtrak train was set off course, spilling off into the high speed roads below. Following the accident, first responders described the scene as horrific. The governor declared it a state of emergency and asked other motorists to avoid the use of the interstate. Three people have been declared dead, while more than 100 people injured in the train and vehicles underneath were transported to nearby hospitals; among them, four suffered serious injuries. President Trump was briefed on the incident and tweeted out about the incident that America needs to invest in infrastructure. Ten minutes later, he addressed the victims and their families, saying he was sending his thoughts and prayers. Other federal officials offered their condolences online and on television.

Details are unclear at this point, but certain facts have been released to the public. It is known that the 77 passengers and seven crew members were travelling along a new service track for the first time. In the following weeks, more information will be released as inspectors from the National Transportation Safety Board and others head to the scene. It is yet to be discerned whether the speed the train was put at by conductors or the new track was the root of the problem.

As the week goes on, the nation will continue to keep the victims of this incident in their thoughts and prayers.
