Yep, as Joe pointed out, it has been done in the analog past. Sometimes old things are new, again....... I haven't ever hooked it up and tried it, prefer the Command Control and conventional, myself. But, when it gets to the point of removal of the "interaction" between trains and the operator, that is where we need to perhaps reconsider. The use of Alexis may be a good curiosity, but IMHO, perhaps no more than that. Even when Neil Young developed the train control system for his disabled son to run the trains, he still maintained an amount of interaction. This, of course, was developed into Command Control.
