While Union Pacific is double the size, Norfolk Southern operates the 960-acre Brosnan Yard in downtown Macon.

Union Pacific is nearly double the size of Norfolk Southern, but in Macon and Central Georgia, Norfolk Southern's presence can be felt at Brosnan Yard.

The rail yard has been a long time coming, with initial work started in 2008 by Palmetto Railways, a short-line railroad that's part of the S.C. Department of Commerce.
