This is the BNSF line that goes up the Columbia River Gorge at Washougal, WA. The BNSF employee (who TOTALLY didn't give me permission to do this) told me that a crew on a passed train saw this and raised holy hell on the radio. The crew on this train slowed to a crawl until they could cut this car out on a rip siding. There was a crane coming to lift the cover and reset the coils. Until the cover comes off, they don't know exactly what caused the shift.
