Max,
I don't have a trackplan although I will do my best to describe it. The main tabletop is a "standard" oval of track with 0-42 curves. One Ross switch comes off of that for a long siding. A Lionel 0-27 switch is at the end of the long siding breaking the long siding into two small sidings. The tunnel covers about half of the layout. The upper loop is a simple 0-27 oval with one Lionel 0-27 switch tucked in for a small siding.
Hope that helps...let me know if you need more help. I may be able to dig up some pictures on my Facebook page or past forum posts to give a better glimpse. Unfortunately my camera lost a fight with a hardwood floor recently and my computer lost a fight with a roasting pan filled with turkey grease so both are out of commission for the time being.
