Autoracks are generally free of graffiti, though this is changing. Most graffiti is on the lower few feet of the car above the side sill. Occasionally, the whole side of the car has been painted. Graffiti guys must show up with ladders to do their painting!
Rails on the secondary track are very rusty. There is very little ballast on the secondary and no raised profile to speak of. Ballast is certainly not in a tight band along the track. Ballast appears to have been haphazardly spilled and spread on the secondary. Sometimes tops of ties are covered. Ends of ties are mainly buried.
Color variation on the concrete includes painted out graffiti. Usually there will be multiple overlapping patches.
