Exactly. And, as it says on the side, it hauls parts for a 747. These have been around almost as long as the 747 itself, although most of the hoods lost the fancy lettering years ago.
LBF made N scale models of the thing years ago, but I always questioned their accuracy, as the hood fills the entire car. In the few prototype pictures I'd seen there is a space at each end for the brakeman to stand. I've never found a way to shorten the hood and keep the lettering. As the GN cars are the only ones I have prototype pictures of, I always assumed LBF simply screwed up.
I notice this car doesn't have the platforms, so apparently LBF is correct after all. And that looks like the GN's cars, which were in the 607xx series. Maybe there were different length hoods? Certainly there were multiple variations on the lettering.
