To add more information, I have about 120 or so cars "live" in the system either in the staging tracks or active on the main layout.
Right now I have no trains built and all previous runs terminated. If I pull up the cars page I find only about 15 cars with destinations listed, most of which are ones with a "return when empty" set. Therefore most of the cars previously dropped off at the classification yard have no listed destinations. I would expect that most every car that is not in staging should have a destination, shouldn't it?
If I build trains it then assigns destinations to cars, including those in the classification yard. This is the crux of my question, shouldn't all cars have destinations BEFORE they go to the classification yard so they can be put into the proper classification tracks upon dropping off? Or am I doing something wrong?
All spurs have schedules and custom loads although the schedules have both custom and the standard "e" and "l". Should I NOT assign "e" and "l" to spurs? Should I totally remove "e" and "l" from the cars loads?
