What are these? Any models?

Found these hoppers on Google Earth in Beaumont. They obviously unloaded at the aggregate facility at the docks there, but does anyone offer anything close in N scale? I see  at least 3 variations in the cars, as there is a long string of them on the yard tracks nearest the street,  luckily.

VULX 6000-6099 are Freightcar America 2518 cu ft aggregate gondolas. Outside dimensions of 42' 1" long, 11' 1" tall, 10' 1" wide. No known exact models of this car in N scale.

FURX 340136 is a bit harder for me to find data on, but it looks like a National Steel Car gondola. Listed as 2480 cu ft, outside dimensions almost identical to the FCA gons. Again, no known exact models of this car.
