It’s a normal, unremarkable scene: A freight train runs along the edge of a parking lot next to a hillside. The sort of thing you see all the time.

Until the hillside gives way.

This happened yesterday in Everett, Wash., just north of Seattle. The Seattle Times describes how it happened:

The surface slide came off an oversaturated 100-foot cliff that geotechnical engineers had been scheduled to check right after the 66-car train passed, according to [Burlington Northern Santa Fe] spokesman Gus Melonas.
