Hate to be a noodge, but I don’t think that’s a sinkhole. The terrain in the background is lower, and this is a slump or a slide off the edge of the higher ground.

You are right. The overhang slid onto CSX tracks beneath. Gonna be one heck of a clean up.

Local DC news showed pics of RR tracks being cleared and CSX hoping freight line open tomorrow....

Odd, seeing as the same report said the houses across the street probably would be uninhabitable for the next few days.
Maybe they are ‘afraid’ of more washouts further under road.

Would think that if RR below slide area, the vibrations etc would trigger more slides....
