Rusty, Nice work so far! Thank you for sharing your progress. The pictures and explanation are great and I think everyone benefits from seeing what you are doing.
If you don't mind, can you add a few more details about your layout's overall concept, like what you are planning for a track plan, the area or time period, planned scenery, etc.? Also, it looks like you are using modular benchwork - what sizes are the modules and what height is the layout? If necessary, will the layout be easily moved in the future?
Thanks!
Mike A.
