Mark, read your opening post, and the question is, is the transition era the most popular era to model? I just don't know! What I do model though is the transition era! My favorite engine is the GM FT demonstrator #103. My next favorite will be the Athearn demonstrator A-B set 1950 when it comes out and it's in my hot little hands! I like the style of the covered wagons. A style you just don't see today! You can guess what railroad I model,(hint hint, look to the left,) I have several FT & F7 A-B sets with several GP 7's GP 9's & Alco RS 1's & 2's, (throw in a demonstrator GP7 in there,) and no steam! I just don't care for steam. I have 1, two truck Heisler for my logging railroad and that's it for steam. Also, you will not find a passenger car on my layout because I don't own one. Passenger operations don't do a thing for me. I like the trans. era vs modern for the smaller cars and the details they have like roof walks. I like cabeese! I don't care for vandals! There are some talented people out there, too bad it shows up on the side of a freight car! But hey, things change, I didn't know that I liked switching ops until I got my layout powered up and did some switching in the yard, and now I want to expand my yard for more switching. So, maybe later on I might at least do steam, I doubt I'll do the modern era...…….
