Dozens of policy makers and emergency responders filled a room in Lakewood at the Clover Park Technical College on Wednesday to discuss the latest threats and safety measures involved in increased oil train traffic throughout Washington.

The Oil Train Safety Symposium was hosted by the Pacific Northwest Economic Region's Center for Regional Disaster Resilience.

The panel of speakers included a variety of experts on changes to train structure and ecological response protocol.

The United States is producing more crude oil today than ever before in history. The PNW has become a major terminal for refining and export, but that has added to the potential to wreak economic havoc if disaster occurs with derailment or explosions.

The goals for the symposium included discerning best safety practices and serving as a catalyst to strengthen relationships between regulatory bodies, the private sector and first responders.
