You can use a BlueRail board to control a DC train layout and up to 4 lights or accessories from your smart device. Use the diagrams below to see how to easily modify a 9 wire harness and connect a power supply. This is a great simple solution for HO, N or even Z train sets. You cannot control separate trains independently, but you can control either a single train or multiple locos as a consist.

You’ll find this in the board “Settings” screen by clicking the little cog on the train control screen.
