I watch youtube videos. I like hi rail layouts so I'll my comments are for them. I'm not knocking it but I am surprizes how many have sharp S turns. or several switches one after another on the mainline. Seems to work alright.
I have open grid and I'm beginning to think I'll never finish it. Table top has to be a lot faster. There are some tabletop that look really nice.
And plaster work, mountains, waterways, bridges, tunnels some have none but look good.
I'm talking about the average home layout here not the famous ones.
