On April 3, 2016, about 7:50 a.m. eastern daylight time, southbound Amtrak train 89 (train 89) struck a backhoe with a worker inside at milepost 15.7 near Chester, Pennsylvania. The train was authorized to operate on main track 3 (track 3) at the maximum authorized speed of 110 mph. Beginning on the morning of April 1, Amtrak had scheduled track-bed restoration―ballast vacuuming—at milepost 15.7 on track 2 on the Philadelphia to Washington Line. Track 2 had to be taken out of service between control points Baldwin (milepost 11.7) and Hook (milepost 16.8) for the 55-hour duration of the project. As train 89 approached milepost 15.7, the locomotive engineer saw equipment and workers on and near track 3 and initiated an emergency brake application. The train speed was 106 mph before the emergency brake application and 99 mph when it struck the backhoe. Two roadway workers were killed, and 39 other people were injured. Amtrak estimated property damages to be $2.5 million.
