It's a bit hard to tell from Athearn's images. Do these two new cars have separate grab irons and other detail parts, or the usual trainset blobs of plastic?
Garth, I expect the gondolas to have separate wire grabs, but the covered hoppers to only have wire grabs on the end sills, while the ladders and slope sheet grabs will be cast into the body. But it is possible to make fine scale plastic ladder rungs, so this may not be a problem. They don't say anything about the running board however.
