GGNInNScale
Granite Gorge and Northern Again
We built the GGN in HO scale twice when I was younger... So, now a bit older. I took the old Atlas "6 HO Railroads That You Can Build" layout and added to it.
It is about 5 1/2 feet by about 4 feet. You can see the GGN in the core, with a yard and engine house, and a perimeter ring for passenger trains. It is a "crossroads"- all railroads are welcome...
Still working on scenery. The switches are controlled by Arduinos- 5 UNOs and 2 MEGAs, the traffic lights in town are synchronized, also controlled by Arduino UNO. The NCE PowerCab runs up to 6 trains simultaneously (concentration needed!). Train location is monitored by Azatrax IR sensor sets, which also control the crossing bucks, block signals, and light the block indicators on the control panel. I have not connected to JMRI yet, but have the NCE interface and a spare computer.
