The Vidalia Union Depot was a splendid piece of architecture that, sadly, was leveled in the 1950s. The historic Georgia & Florida Railroad operated on the tracks to the front right in this photo.

The dot here shows approximate location of the Vidalia Union Depot. The dashed line shows the historic Georgia & Florida Railroad tracks, now abandoned all the way to Douglas, GA. All together, approximately 130-miles of the original 250-miles of track from Augusta GA to Madison FL line is currently abandoned or converted for recreational use.
