I was watching about how to set up a switch. I notice they had to hook up the electric wires all the way back to the power source. With the latest technologies that are out there, I wonder if companies like Lionel/MTH/Atlas would make the leap and use something like bluetooth to trigger the switches and depend on only the power on the track.
Not being an electrician, is there not enough power on the track to support a Bluetooth switch? Heck, maybe some wifi or something like that? Unless that is part of the fun of setting up a track where you wire everything up.
