The BNSF railroad tracks in Montgomery county, Texas, run underneath some high tension power lines. There are three hot lines on those towers and when the utility unbalances the load on the lines, it induces enough energy in the tracks to blow out the track side equipment.
I was there at an insulated joint and, by connecting a wire to one side of the joint, you could write on the other side using the arc. This was when things were normally balanced.
Interesting. Those bond wires are of a substantial gauge size.
