Accident reports obtained by The Times contradict a 2013 Georgia Department of Transportation assertion that five fatalities have occurred as a result of collisions between automobiles and trains at the Tumbling Circle railroad crossing in Hall County. And concerns about public safety appear to be just one reason why the DOT has ordered the crossing to be closed. Barricades were erected at the crossing last Friday, and Norfolk Southern Railway plans to place a permanent guardrail at the site, perhaps as early as this Friday.
