Sagging track, (click here) the flood came thru. Beneath the track you have a view. The rare but heavy desert rai 

It worth checking. A flood washed out the sandy soil under the railroad tracks. The track caused enough agitation of fast flowing water to cause erosion. Rain isn't suppose to occur in the desert, there is no way of knowing there is impact without inspections.
