modified because an automation discussion on MRH:https://model-railroad-hobbyist.com/node/42657

1. Staging width increased to 8 inches
2. staging simplified & increased to five tracks
   1. The length of the staging track was increased to maximize the number of trains in staging
   2. This moved additional staging turnouts into the corner T-track module areas.
   3. This has been rectified in the upper left corner
   4. The right corner is just a turn around tack on this build
   5. There is an issue in the plan on the upper left side where two tracks are very close. That will require more work.
3. Track details have been modified to reduce the number of small sections.
4. module outlines show how they are configured for initial build.
5. support issues required the right turn around be moved to the south east corner
