Hello Everyone. I'm new around here. So, I'm into the 1975-76 American Freedom Train, and I wanted to make a Model of the AFT in G scale (The full 26 car train.) I've been using a website (I can't add a link as it won't post) as my resource, but the biggest issue is, I don't know what to use to make the 26 cars! (except for the flat cars.) the only thing I know is available is the AFT GS-4 that MTH released a few years back. can I have some help?!
