On June 27, 2017, at 11:18 p.m. eastern daylight time, two CSX Transportation (CSX) employees (conductor and conductor trainee) were struck and killed by southbound Amtrak (National Railroad Passenger Corporation) train P175 at Amtrak milepost (MP) 134.5 in Ivy City, a small neighborhood in Northeast Washington, DC.1 The two employees were on the track walking toward the front of their southbound train after inspecting a railcar with elevated temperature reported by a track-side detector. Their backs were to the approaching southbound Amtrak train when they were struck. At the time of the accident, the sky was clear; visibility was 10 miles, and the temperature was 64°F. Additional ambient lighting was provided by a nearby Amtrak maintenance yard.
