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.
Please scroll down to read entire desciption.
Use with my latest version of route Powder River Basin-97 Complete v4.
Found a few more schedules that needed correcting(12-10-18)?
Added more schedules and corrected others.
Changed some trackmark call outs for latest version of route.
Open Schedule Library in 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.
Any comments, ideas, or suggestions go to Trainz Forum and let me know.
