Last evening I made a first run on the layout with a temporary lift out bridge handling the opening to the center and the temporary trestles. Here is the liftout as RSJB18 Bob suggested.
Here are a couple views of the layout, one from the door and the other from the window over the washer and dryer.
Here is the first run video running an MTH Premier SD40-2 and Lionel caboose. Later in the evening I switched in the 5 hoppers on the siding but didn't video.
