About 10:45 a.m. on July 23, 1984, National Railroad Passenger Corporation (Amtrak) trains Nos. 151 and 168 collided head-on on Amtrak's Hell Gate Line in the Astoria section of Queens, New York, New York. Train No. 151 was being operated by train order authority westbound on the No. 2 main track between Market Interlocking and the east end of Gate Interlocking. Train No. 168 was supposed to have been stopped and held at the home signal on the No. 2 track at the west end of Gate Interlocking for the arrival of train No. 151. However, train No. 168 did not stop at the home signal but continued past Gate Interlocking. The two trains collided about 1.1 miles east of Gate Interlocking. One passenger was killed; 129 passengers, 8 Amtrak operating crewmembers, and 3 Amtrak service attendants were injured. Property damage was estimated by Amtrak to have been $3,199,000.
