That layout is meant to be operated from the outside. The center of the U is an area my wife needs for her projects. If you still want the specs I can send them. A couple of the turnouts are intended to be hand-layed.
Nice job on my layout spacemouse, although I must admit my somewhat limited knowledge of railroads prevents from seeing the purpose of some tracks.
the 2 tracks that were my yard lead and engine servicing, are they both servicing now?, they seem to be too short for a lead. Would I use the track that heads back to the mainline as a lead?
Also the extra yard track that is separated from the other 3, is this some sort of repair track? or caboose area?.
and lastly the extra track in the bottom right hand corner that is parallel to the bottom table edge, not the staging area, what is that? some kind of interchange maybe?
And the staging track that led to the mainline, are the 3 tracks that that branches into storage for trains?
