It is a program developed by forum member skylark and It is used in conjunction with CTI Train Brain software and a hardware interface box. I wish I could expound better itself it's capabilities but I am brand new to it and just beginning to get my feet wet. I do know that as technology challenged as I am the fact that I was able to fire up the DCS, then the PC and click on an engine and it started immediately says something about it. I know there is a lot of functionality built into it and a few different methods for operating your trains. If you are interested then I would suggest you contact skylar and he can fill you on the details. You will find him extremely friendly and helpful.
