Nice video, this is inspiring me to try kitbashing when I start making my layout. Also you were surprisingly accurate with the GN O-8 since the GN almost had a tractor tender loco. It was going to be a 2-6-2+0-6-2 using the wheels and frames of two J-1 Prairies, there were to other ideas to use an O-1 and F-1 to make a 2-8-2+2-8-0 and an M-1 and a six coupled engine making a 2-6-8-0+0-6-2.
I love it! Keep it up and how about a "CHALLENGE"? Build a SP cab forward Challenger 4-6-6-4. Even better what if the UP somehow got hold of a couple ATSF 2-10-4's, what would they have looked like? Really liked your American Garrat.
