Train Loading and inserter on circuits

[ArgTang]

Hi i dont understand this. I read it was fixed, so it must be my understanding that is lacking.

I want to make a builder train that load lots of different items onto a train based on the read content. To restrict each of the slots in a cargo wagon is tedious, so i hoped i could do it with some simple circuit conditions. The inserter ALWAYS does at least one loading, even if the wagon has all the required items. this breaks the whole system, i have tried to put the inserters behind a power switch that activates when a train arrived, but that does not seem to help. I can add combinators, but in my testing i would need TWO combinators for each item, witch is more tedious than before.

Does anyone know of any good solutions?

The fix was to add a unique signal that you can check to see if the train is missing.

Yes i have used that to toggle the power poles, as i tried explaining. I dont power the inserters until a train gets to the station

Use something like this to turn off all inserters.

Thanks DaveMcW!

That works! its an unituitive gamemechanic, so i hope they can make it better.
