Around how many freight cars can a GP7 realistically pull?

Thanks everyone.

I'm using Atlas code 100 tracks. My turn-outs are all Atlas Snap switches. Also, I don't have any grades, so my layout is basically flat.

I think I'm about to give up on that 4-8-4. These steam engines are giving me a pain. hehe. The 0-6-0 works fine, though.
