7000 series train causes smoke at Eastern Market

Today Metro had another problem with a 7000 series train

According to WMATA, an assembly box on the side of the train, which was a 7,000 series train, came loose and was rubbing against the third rail. The third rail is the electrified line running along the track, which provides power to Metro trains.

When that happened, electricity began to arc from the "third rail shoe assembly," which is the part of the train that connects to that electrified track, WMATA said. That likely led to the fire and smoke.

The train was not derailed at any point in the process, and the arcing is not a known fleet-wide issue, but "inspections continue," according to WMATA.

Inside word is train hit something that dislodged the box, no management scramble here like I would expect if it were a rail car defect. Must have been something fairly substantial to shear the anchor bolts or welds depending on the box
