I am very confused as to how you are getting this error. I checked the two '70's template activity files, and they do not call for car type TIE. The two '80's template activity files do have TIE as a car type, but these also have TIE cars designated in the SWLACT files, so you should not get this error. TIE is a car loaded with railroad track ties. In this case, the downloads include four center beams which are loaded with ties.
I'll look at some other things today at lunch time to see if I can find the source of this error.
Please advise which activity file is giving this error.
Given this, it sounds like it could be a Train-Store issue. If you store the rolling stock before generating the activity with AG, sometimes the rolling stock needed gets stored. If you do use TrainStore, try this:
1. Use UnstoreEverything!
2. Generate your activity.
3. Now store everyting but that activity or everyting but that route.
This may correct your problem.
Thanks,
Steve
