Make that about 70% accurate Tim. The ends are wrong and the fishbelly underframe is essentially 100% wrong for the IC cars. Still, if you need more than one for your IC roster (like I do!) it's a whole lot more affordable and quick than the Sunshine version of the same car.
Avoid the Walthers 50 foot SS box car. One way ticket to Foobie-ville.
Again, unless you need IC cars. Then the Walthers model, with minimal kitbashing, becomes the only accurate IC 50' SS boxcar ever produced.
