BNSF 4904 leads NS P61 through Barber, NC, exactly one mile west of the crossing of NS's S-Line between Salisbury and Asheville and L-Line between Mooresville and Winston-Salem.
The second of three consecutive trains through Barber with BNSF power leading is NS P61, slamming the diamond at Barber Jct. They'll soon meet eastbound 139 running with a pair of BNSF Dash-9's.
