The North Carolina Railroad Company (NCRR), Norfolk Southern, and the North Carolina Department of Transportation (NCDOT) are preparing to replace rail lines in Guilford County next month as part of the Carolinian and Piedmont Passenger and Freight Improvements (CAPPFI) initiative. The upcoming rail replacement phase will affect several rail crossings primarily in eastern and central Guilford County with temporary, days-long closures. Crews are expected to begin work in the county in late September to early October.
