At 2:38AM Eastern Standard Time on January 6, 2005, NS freight train 192 (lead by SD60s #6653 and #6593) approached Graniteville at approximately 48 miles per hour. Train 192 entered emergency braking when the engineer saw the improperly aligned switch, but there was not sufficient distance for Train 192 to stop. At 2:39AM, Train 192 was diverted by the improperly lined switch onto the siding and collided with P22. The collision derailed both lead engines, 16 of 192's 42 freight cars, and one of P22's freight cars.
