March 2008 - Now that the Helix is up, have to give the trains somewheres to go. Started shelfs at door top height. Shelf will go half way down the side of the room, cross the room in the center, then back up the other side, and re-cross the center, and meet up with the inner track of the helix. Shelves are 1 inch boards, notched to overlap for added strength at joints. Corners are 1x12 cut at 45 degrees, and notched to overlap the shelves.
A G-scale shelf layout is planned for the other half of the top of the room.
