Thomasville's "Train and Railroad Live Stream Camera" may be viewed at the following web address:  
visitthomasvillenc.com/train-camera
Once you are there, you have two choices: a North-facing camera to best view southbound Amtrak trains (currently 73, 75, 79, and 19) and a South-facing camera to best view northbound trains (currently 80, 74, 76, and 20.) There are NS freight trains, too.
To be ready to view a passing Amtrak train (they don't stop and are traveling at speed, so don't blink or they've gone by) start viewing at the following times every day: 
80 Carolinian - 7:47 am
73 Piedmont - 8:22 am
74 Piedmont - 11:29 am
75 Piedmont - 11:52 am
76 Piedmont - 4:14 pm
79 Carolinian - 7:35 pm
19 Crescent - 12:42 am (Mon/Wed/Sat only)
20 Crescent - 3:01 am (Mon/Wed/Sat only)
This assumes that the trains are running on schedule at High Point. Be patient; you will likely have a 5-minute (or longer) wait before the train appears.  
THOMASVILLE IS THE ONLY LIVE RAIL CAM IN NORTH CAROLINA RIGHT NOW
NCOT and CAPT are currently assessing the feasibility of adding rail cams at several North Carolina Amtrak stations. 
​Not only do suitable high-mounted camera locations need to be found with unobstructed views of the stations, but local governments and local businesses will have to be "sold" on the idea as a promotional tool.
CAPT is receiving valuable initial guidance from the company, Virtual Railfan , that  operates the Thomasville camera, regarding parameters for camera location, orientation, and distance from the object of interest. 
As progress is made, updates will be posted on this page.
