On Saturday I encountered for the first time an actual derailment of two of the three GP units used by BNSF in the “west yard” at Eola (actually Aurora, IL). The third unit was still on the rails and was used by the large crew there to help re-rail the two units that went on the ground. The whole process took approximately two hours to complete with “re-railers” and was quite interesting and impressive to me. Photo below of the three units during the re-railing (photo was taken by Nick Hart and credit goes to him for a fine job).
That was my first thought as the derail was right under the middle unit when I arrived on the scene and the crew needed to have the “lead” unit (the one still in bluebonnet scheme) haul the other two beyond the derail before beginning the rerailing process. By the way, the derail you see here is not powered but has always been manually operated.
