Need Help - Looking for Yards in Winston-Salem NC Area

Any help is appreciated on this one. My Boyfriend is an Conductor/Engineer up North and is looking for RR Yards in the Winston-Salem/NC Triad area. I have only been in this state for a year and don't really know of any except for NS Linwood and Greensboro yards. Any RR with a yard in the area would be very helpful! Hope to get some good information and thanks in advance.
