Can someone help me identifying this type of car, and tell me if it has ever been made for Trainz?
I found this picture on Flickr this morning, and I saw five of them in a Youtube video some days ago. In the video, these cars were at the head end of a Union Pacific autorack/TOFC train, so I believe they are used for some priority freight. I initially thought they were BN boxcars, but there is no BN logo and the sides look like those of a stock car.
Unfortunately, I've been unable to read the reporting mark on the side: the last letter looks like a "X", so they should be privately-owned cars. The car number has 2 digits only, so I presume that only a small number of these car exists.
Thanks in advance.
