You didn't happen to get any pictures did you?
I've been searching all over for the ACe & M-2 shots. I've found thumbnails on train orders, but I'm not paying to see a picture.
I hope Athearn DOES release a spine. Those Maxi-I cars are SWEET, so I'd guess the spines will be too!
Sorry man I didn't have my camera with.. I've only been waiting 2 years now for the UP Heritage engines all on back order, delay after delay.
