One question I have, when you say full automation do you want it where you basically have trains running on the layout and have software that literally just lets you sit back and watch the activity? So for example, if you have engine(s) running a particular train, that the software would control the engine, that if it was going to enter a block with another train on it it would stop or slow down, would the program know where the train is going and throw the switches to the proper direction, and if a train approached a switch set the wrong way (Ie coming off a branch, would throw the switch to allow it to enter the main?
To me that would be full automation (and approaching this as a path theory problem would indicate to me specifically). Asking this out of curiousity but also it may help others reading this know what you need.
