Hello all, it's me again,
I relocated the hinges from the bottom to the top of my access panel. When lifting the panel I create about a quarter inch gap between the two tracks when the panel comes down again. Please look at my pictures and see if you can come up with some type of solution or is this gap acceptable. As noted before tree sections of track will be located coming across my access panel. I also added an overall picture of part of my layout.
Thanks again for your great help, Jerry
