The section of the original Manassas Gap Railroad between Strasburg and Manassas, Virginia continues to be used a busy freight line, called the B-Line of the Norfolk Southern railroad, with the heaviest traffic between Front Royal and Manassas. Since the 1999 breakup of Conrail, when Norfolk Southern acquired the Lurgan Branch from the north end of the Hagerstown District into Pennsylvania, the B-Line east of Front Royal has been a major connection, allowing traffic on the Washington District to bypass Washington, D.C.. The B-Line supports mainly intermodal and manifest trains, although beginning in late 2018, Norfolk Southern began running coal unit trains on it more frequently than before.
