Yes, Had boxcars, the PICK XXXX were mostly painted in a Bi-Centenial scheme. Also had a bay window caboose and combine that I never saw move once in the 24ish years I lived in the area.

The locomotive roster is very hodgepodge. The only locomotive I have seen modded in game is the B40-B. The only photos I can find of these are still in CSX colors, minus the CSX on them. The rest of the locomotives don't exist in TPF2 yet. I'd like to see a B40-8 in Pickens blue like PICK 2 was though if it is possible.

I remember growing up seeing them when we'd go from Easley to Pickens, sometimes working the mill or cement plant. Later the only thing they moved was older locomotives to their shop to rebuild them before that line was removed out of service and turned into a trail. Their other branch, I have only seen photos of.

@Vulgaris Magistralis - "...stuff for Pickens"? Would you give an example.

Finally a few more SC based locomotives. Now if someone could create some stuff for Pickens, grew up seeing this stuff.
