I designed the following building back in 2020 (can't believe it has been that long) and have had the print files up on thingiverse since then with 4700 views and 3300 downloads. I've printed a couple myself for the layout but have never painted them as the layout isn't far enough along to place them yet.
Ed started helping a couple months back and has been painting vehicles and a few other things. With hardly any of those left he is going to start on buildings and choose the freight building as his first. He is really getting the hang of painting (all brush so far) and I wanted to share his work with you guys, so.....

N Scale freight transfer building with ....

........ one side facing the track along side it. On the opposite side .....

........ and on one end are loading docks for trucks/trailers to unload/load at.
