One thing I'll say, and the last of this route I'll post in this thread before making my own, car going to the staging tracks of Toledo and Saginaw have 0 time on them. This means once clicking delivered they are ready for pick up. Best thing to do at the start of the session is to assign the cars on the ECS track records. Then deliver them to Toledo or Saginaw with the SD40 that is in staging. Then you can run Q322 from the Toledo track, to Plymouth, and then to Flint.
This weekend I'll add a few more records and more rolling stock to increase operations.
