I put together a compilation video of the 3x5 N scale layout. This video combines the series into one video, with the beginnings and ends of the videos, recaps, etc. stripped out to make it a shorter view time.
There isn't any new content in this compilation video, but these big compilation videos do better on YouTube with non-subscribers in terms of total views. Plus, if you want to rewatch the series, it puts it all in one video.
