Amtrak 74 has a NCDOT Cab Control Unit 102 on the rear on its first solo trip. This was rebuilt from a GO Transit F59PH by NS in Juniata. It and sister unit 101 are now in service on the south/west end of some Piedmont consists.
Three north-south routes cross the Carolinas. Auto Train runs through here, too. Also, the State of North Carolina sponsors the Piedmont service and supports the Carolinian.
