Detect if Train Stop Open

[Midge]

I have a train that has the following route:
1. Steel Pickup
[Wait until 5s of Inactivity]
2. Stick Pickup
[Wait until 5s of Inactivity]
3. Waiting Cell
[this is what I'm trying to figure out]
4. Steel and Sticks Dropoff
[Wait until Empty]

This train picks up sticks and steel for the production of rails, I have a circuit connected to the station that closes the station when rail storage becomes full. I want the train to detect when the station opens so it can leave the waiting cell to deliver the now needed materials.

You need to alter the 4rth station so that instead of open close, you set the limit from 1 to 0.
1 sec inactivity on the 3rd station should be good then.

This works if you only have 1 station called "stick and steel dropoff".

The train will see it with limit : 0 and will wait at the previous station (the waiting one) until the limit is not 0 anymore.

Then when empty, the train will go pick up steel
then stick

then go wait 1 sec, but will see "0 limit" for the next station on schedule, so it will wait.

I assume you have set filer on wagon.

Thank you so much, it worked

Thank you so much, it worked

glad it worked for your purpose

Another way to do would be to have the train in the waiting area waiting for a signal condition to depart for the dropoff. And then use a wire to transmit something like 1 green signal to trigger the train leave condition when things are missing in the dropoff. That require the dropoff and the waiting area to be connected via a potentially long wire but it could allow to "call" different train based on different missing things is you send different signals, like 1 green if you miss steel to make the steel train stop waiting and delivers instead, and 1 red if you need stick to make the stick train stop waiting .
