The first round of public comment on possible passenger rail service between Atlanta and Charlotte, N.C., is coming to a close. The Georgia Department of Transportation will accept input through Saturday, then shut off what is known as “public scoping” for the project, which has as one of its potential routes a Norfolk Southern railroad corridor that cuts through Hall County. Those interested can post comments online at a website set up about the project, email them to a project address or mail them to Glenn Bowman at the DOT’s Office of Environmental Services.
