Track Plan Layout
Next, I laid out the track plan on the base sheets. The corner modules are actually two sheets of 36"x18" material that had to be glued together first. First, I laid out a 3" squares and then transferred the track plan to the syrofoam using a black Sharpie marker. Then, I outlined where the Subterrain riser sections will be placed. The corners of the corner modules still need to be cut off. The next step is to install the profile boards around the modules.
