The Bragg Road Ghost Light (also known as the Big Thicket Ghost Light and the Saratoga Light) is located on the dirt road that runs between Saratoga and Bragg, Texas. In the early 20th century, railroad tracks ran over the road and several deaths supposedly took place here while the trains were still running. The rails were taken up in 1934, and it was after this that the ghost lights began their appearances.
The light seen on Bragg Road is said to sway back and forth, and changes from yellow to white to red as it approaches the observer. Local legend usually attributes the light to a ghostly railroad worker that was killed on the tracks, and indeed the swaying motion of the light seems to match the actions of someone walking with a lamp.
