SEATTLE, Wash. (AP) — Seattle’s transit agency has removed its top safety officer as a result of a fatal train derailment. The Seattle Times reported the Central Puget Sound Regional Transit Authority removed Salah Al-Tamimi as its chief executive safety and quality officer. The CEO of the agency better known as Sound Transit says Al-Tamimi may take a lower-ranked position. The decision was related to a fatal Amtrak Cascades derailment on Sound Transit-owned tracks in DuPont in December 2017. The National Transportation Safety Board placed primary blame on Sound Transit for failing to require safety improvements where the derailment occurred.
