On September 25, 2014, at about 5:44 a.m., eastbound Union Pacific Railroad (UP) train ILXG4X-22, collided with the side of westbound UP train KG4GSX-23 near Galva, Kansas.1 (See figure 1.) The westbound train was entering a siding, but it had not cleared the main track when it was struck by the eastbound train.2 Five multi-platform intermodal cars derailed from the westbound train. Two locomotive units and four multi-platform intermodal cars derailed from the eastbound train.3 The UP estimated about 200 gallons of diesel fuel leaked from the fuel tank of one of the derailed locomotives. No crewmembers on either train were seriously injured. No fire resulted from the collision.
