Can Amtrak & Metro equipment run on the same track?

Is that Amtrak track, or some railroad track?

The amount automobile of traffic on the I 95/295 corridor would indicate the line would be oversubscribed from the moment it opened.

It seems reasonable to me that Metro run lines to high density population centers like down the I66,i95(n&s),dulles, and rt 5 coridors.

The rich people up in far NW have their Metro, the poor people on the east side need one also.
