I love old railroad photos like this. You’re looking at a couple photos of the Alexandria railroad roundhouse back during the Civil War. They’re just beautiful photos, frozen in time, so make sure you click on them for a larger, more detailed version. You’ll love them.

Photograph shows a locomotive moving away from the roundhouse at the Orange & Alexandria railroad yard in Alexandria, Virginia. Railroad signal lights on pole in foreground.
