Okay, I give up.  Selected a driver and assigned him a loco.  Selected Drive Session and I wind up in the middle of a body of water, not at the loco.  Why?  Next question, how do I access the Drive Command Menu?  You know where the drop down selections might be Drive To,  Drive to Track Mark, etc.  Use to be upper right hand corner but I can't find it now.  Feeling kinda dumb right now.
