About 3:35 p.m. on February 26, 1984, westbound Consolidated Rail Corporation (Conrail) Train ENPI-6X, moving about 27 mph, struck the rear of standing Conrail Train OIPI-6 at Control Point (CP) Salts on the No. 2 track near Saltsburg, Pennsylvania. Derailed cars from train OIPI-6 were struck by eastbound Conrail train TV-12M which was moving about 38 mph on the No. 1 track. When the collision occurred, the derailment of a car in train TV-12M caused its brakes to apply in emergency. Two cars and a caboose derailed in train OIPI-6, 1 locomotive unit derailed in train ENPI-6X, and 1 car derailed in train TV-12M. A fire ensued and severely damaged or destroyed 19 "piggy-back" truck semi-trailers carried by train TV-12M. Two crewmen on train ENPI-6X and 1 crewman on OIPI-6 were injured. Conrail estimated the damage at $784,719.
