well my homemade tunnel portals I thought I did such a good job on with the new engines I have been picking up well the overhang hits them. so off they came. I have been planning a yard of some sort under the middle level of the layout so with the clearance issues and the yard needing done and my switches came in reconstruction begain last night with removing all the track from the middle level. which got me thinking 2 simple loops in this 6 x10 area I can do better than that. also needed to fix where I cut the layout in half to move it a few months ago it supported my weight but just so that needed addressed so out came the saw 
I removed all plywood on the middle level. removed all the bracing. built bracing for the yard and added plywood to it. tomorrow I will add the bracing to the middle level again and put down new plywood. they layout the new track plan up there. here are photos of my labors. it's a mess up there now. also adding in 2 popups to access the middle level.
Now is the time to make these kind of changes. I'm sure you will never regret it. You have been doing a great job, so I'm sure it won't be long you will have trains running on that level again!
