Hi Bob well a bit off present topic of electrical, but there are still a few things to be looked at first. You plan on putting a fair bit of change$$$ into the passenger station and equipment. Now going back previous posts the area at the bottom of the plan was for viewing and I assume entry to the room. You have shifted the station from the center area to the forefront and that is a good move, however unless you plan to have stick people or undernourished viewers and operators I can't see one and one half feet of clearance being enough. It would be a shame for an unintentional blow from an arm or butt to damage or completely ruin the station not to mention any rolling stock parked there. ( Remember Murphy's law) The second thing that comes to mind again is the radius of the loop and the lead to the station. I doubt you will have room for a max radius of 22" and that will leave full length passenger cars looking kind of odd entering and leaving the station.The passenger station will be the focal point of the layout.
