Help needed for prototype based switching layout

Would have the Humbolt yard lead be the "tunnel" track. As you have it drawn now most trains leaving the yard will have to saw back & forth to enter/leave the yard.
In Jefferson you have two sidings when you really only need one. Also would shorten the lead into industries in upper left as it looks like there's not of room to right for all possible cars in there. Wold change spur to industry in upper left being off the siding w/ LH switch & maybe Xing the lead to upper left industries.
