A flash
As I was walking to work this morning, I heard an approaching MAX train. The arm on the overhead wire was sparking as it passed aver the splices in the wire making a bright flash. All very normal for a damp day in Portland. I watched as the train passed and, for the first time, noticed the electric sparks jumping from the wheels to the track. At first it was unexpected but after looking up at the single overhead line it made sense.
