I think that running P-glass beyond the corner modules would be okay. My Railking 4-8-4 fell off the table after passing thru the corner. Regarding skyboards, We still need to have an open space in the middle of straight modules or all corners. I walked around on the inside and still couldn't see my train half of the time. There are too many distractions for us to constantly monitor all the trains. I think that mirrors might be a liability unless they are well secured. Lowering the legs is not the answer as Bob will testify. It is just the right height for us to work on and still save our backs. I think the idea of a walk thru module would be most beneficial. I will work on a design for it. The power loss is not just on track 1. I was running on track 3 and noticed a loss on 4 or 5 modules all afternoon. It started at the transition module and went thru the swamp to the next straight module. It returned to normal after entering the second straight module.
