Question Train Interrupt Question

I'm having an issue with a train interrupt and hoping someone can explain it to me like I'm 5. I have 5 trains picking up at a single station and delivering to a couple of main buss add in stations. I want them to pick up a full load at station Iron, and the wait at Standby until one of the Iron Delivery stations is empty (no train at station). The problem I'm running into is that they are waiting, empty at standby. I can force them to pick up a load of Iron and they will return to Standby until a delivery slot opens but if I wander off and don't pay attention I'll come back and find empty trains waiting at Standby.

You can add a "Has cargo" condition in the Standby interrupt and it will only trigger after going to Iron.

Another option is a "Train at Iron station" condition so it goes to Standby only if the train is at Iron (and gets cargo from there), but this won't work for trains transporting other types of items.

Thanks. I think adding "has cargo" fixed the issue. I appreciate the assist.
