Obviously the quality of the model railroad highlighted in the video is very good... Someone or someone(s) has invested an awful lot of their time bringing that layout to such high quality.
Ed's point is well taken. The images found in his links are jaw-dropping. The work is top notch.
The challenge is taking what we see in images like these (and the many others posted on this board) and expanding them so they cover an entire layout... Detailing even a small layout to that level would take a great deal of time. I don't think I've seen a larger layout on here that features the amount of detailing found in those images–It would be an incredibly difficult task.
And then you have video vs. still images– With video it's much harder to "fool" the viewer into thinking what they are seeing is anything but a model railroad.
