Mallard4468: Mike G made a great suggestion which was we should have done a walk around with the video camera, but in lieu of that, here's some overhead photos down below, which may fill in some of the blanks. Sorry for the mess, I am in the middle of installing all new weathered Pennsy Stone Block Walls between the lower and upper level.
I don't have any photos handy of how the sections are joined. If I can get some photos in the next day or so, I'll post them. The sections, at least the large main ones have two things in common. The joists travel with the section on top of the L-Girder benchwork, and the mechanical joints between sections, are tapered blocks on like a 2 degree taper. So assembly is accomplished by positioning the section up on the L Girder assembly, then pulling it in at the tapered blocks. It forces a perfect alignment. No tracks or switches traverse a joint. All wires meet at terminal strips at the section joint, the only exception is some large multi-conductor cables for the signal system which only go from the main 24 relay control panel to two or three signal signal locations, but the cables are labeled as to which set of signals they belong to.

Thanks for the pics - no need to apologize for the work in progress. Interesting ideas re the sections, as L-girder is difficult to build so that it can be semi-modular. Looking forward to seeing some pics of the sections.
