So I'm intentionally leaving the centre of the room free for a possible n gauge (probably US themed) switching layout, should I ever bore of the Irish Midlands or want to allow guests, but I'm not expecting to any time soon and I get a lot of enjoyment out of the computer automation stuff, which gives a lot of room to try new things out, even though the rolling stock stays Irish. It has too many limitations for what I want to achieve but it was useful as a learning experience. I will not be using any of this hardware except the raspberry pi (and that may be a bit weak too as it's single core) in my big layout. ![]() I had much of the hardware lying around and wanted to try Rocrail. ![]() The loco will then trigger the optical sensor near the end of the block (I have no signals but the signal post would basically be just after the optical sensor) and Rocrail commands the loco to stop. Rocrail then starts to decelerate the loco if the loco needs to stop in that block. The current sensing is used to alert Rocrail that a loco has entered a block. The controller simply routes those back to Rocrail so it can keep a track of loco progress. The yellow patch cables carry the s88 bus (it's just a long bit shift register) signals back to the controller. s88 bus board for reading optical sensors in and reporting back to controller. openDCC based point motor controller (basically homemade using openDCC processor from their solenoid motor controller project). two cheapo point motors at the extreme left and right ends openDCC kit built DCC booster (directly under controller) Raspberry pi model A running Rocrail server (bottom right) ![]() I've recently remounted it here in the basement room where the future layout will go and fitted or refitted the following to the underside: I don't really need this space saving design here but this oval was put together almost ten years ago now and we lived in a smaller place back then. The oval is a simple sheet of framed chipboard, attached at a hinge point to the wall and also attached with two chains that bear the load when the oval is folded down. It's not layout, rather a "test-bed" for different technologies I am evaluating before I some day start my proper layout.
