D&RGW's Tennessee Pass: Start of the Peninsula

Waiting for miscellaneous stuff to do more electrical wiring, layout wiring, track laying, etc. I decided to start on the wall for the peninsula. You'll also see the Hammerhead 360* rotary laser level I bought to help aid in maintaining deck height throughout the layout. The basement floor is not level enough to measure up from and the floor joists were too imperfect to measure down from to keep measurements consistent and verify level. It's interesting to note though, that my first method of using a 4ft level along the wall only yielded a 1/2" difference in height from one side of the basement to the other. Having the laser put a line over the complete basement all at once makes measuring so much easier however. At lower left you see the base for the staging yard. On the peninsula wall you see two strips of masking tape. That represents the main deck and the upper deck levels. The layout here will only be 1ft deep, allowing for a 3ft aisle.
