Use with my route Powder River Basin-98 (<kuid2:526403:102528:2>).

I've changed UP schedules to have trains stop only at Bill yard on their way back from the mines. I did leave schedules for those that prefer to start at Bill and then go to mines.
I also have changed schedules to hopefully make them run smoother.
A blank session where you can put a consist and driver at various locations including portals and use Schedule Library to issue each train a chosen mission. Session also has detector, junction, signal settings, etc..
Open Schedule Library(After clicking on edit session) to understand where each train should roughly begin and where it will go to.
Choose a starting point for each consist from Schedule Library.
The lists or groups are the basic starting point for each train.
Open Driver Setup add driver and where you place commands go to Copy Commands and choose Append or Insert and go to From Library to select schedule(mission).
You can also choose a portal or place a train just after to begin for those schedules(missions), such as Lusk, Moorcroft, etc..
The Schedule Library is for grouping schedules and editing purposes. And although not in any alphaberical order, commands will be when picking schedules.
While this doesn't cover every scenerio possible, hopefully this will give you some ideas.
