You'd think that. As did I, until I talked with someone in the industry. Don't want to go into too many details as it was confidential info. And only applies to the most recent Amtrak paint schemes. Essentially everything after Amtrak and Walthers made their agreement.
That's why I think the new heritage paint sheme will fall under that agreement since it technically is new.
Notice there's no Amtrak California, Surfliner, or IVb from Microscale even though they are hit with requests for these all the time. Hmmmm
We are very lucky to have the P42 phase V decal set.
And yes forgot about Bachmann. They licensed the Acela scheme and variants. Atlas also has an agreement to do various phase V paint schemes.
These licensing agreements are quite complex and just end up hurting the hobby with higher costs and prices (UPS anyone?). But that is my opinion, which should be saved for another discussion topic.
