O-Gauge - LCS SensorTrack
Add the LCS SensorTrack to the mix. Now your LCS App control panels show the location of Legacy Engines as they travel across your layout. And when a friend brings over a Legacy locomotive, simply run it across the LCS SensorTrack and that engine's name and number are immediately updated on your iPad screen and each Legacy Cab-2 remote. Use Sensor Track to trigger preset actions like blowing a grade-crossing signal each time a Legacy engine passes. You can even record your own special series of commands to be triggered automatically.
