Many thanks for all the feedback on my post :-) The radio idea from Nigel would be fun bit looking at the parts needed quite expensive compared to reeds and magnets (so maybe one for another time). Im going to either go with reed switches or 24v AC track circuits. If any body is happy to advise on how to build the logic? im thinking either a PI based solution or using relays? Be great to understand what others have done. Thanks agin for all the replys. James

Hi all I have been building a garden railway G gauge for a year and I am about to move on to Singling using 2 aspect colour light signals. I am looking for some suggestions and ideas on how to automate it. The Railway is used for Battery RC locos and Live Steam and has no track power ( I hate track cleaning ) The track is a single line with a loop at each end and a spur off one of the loops to a station area. My aim is to break each loop in to 2 or 3 blocks (One loop is much larger than the other) and the single line between as a single bidirectional block. My ideal outcome is that the remote drivers can follow the automated singling on the loop and the Station is manually signalled from a control box. I have considered reed switches, Hall sensors and infrared detection but I am open to all ideas and feedback with either relays or a PI and or Arduino to do the logic. Looking forward to ideas and suggestions? Many thanks James
