If you don't already know about it, you might want to check into the new Layout Control System (LCS) sensor track. I'm also new to Legacy, don't have a sensor track and don't know a lot about it. It requires newer engines that are sensor equipped, like in the last 3 years or so I believe. May not be exactly what you are looking for here, but none the less a new and exciting product for Legacy with a lot of potential for Lionel to expand on.
MartyE and gunrunnerjohn are two forum members that know a bit more about it and can probably explain further on it's capabilities and functions, if you ask them about it. It does quite a few new things already. There are others in the know as well, but these are the only two I could think of just now.
