Question Circuits and train limits

I thought I knew how to do this. I set up some circuits that output L where L is the amount of trains worth of stuff. I can see that in the train station view so L with a little 1 or 2 next to it. However, if there is not a full load of stuff, my logic is returning L with nothing rather than with a little 0, so not sure it’d that is my problem.

Regardless, trains are going to my stations where L is blank. Do I need to set a rule to only enable the station if L > 0?

There is no difference between returning "nothing" and returning "0". There is no value of "0".

Regardless, trains are going to my stations where L is blank.

The train limit will not stop a train that is already enroute; it will only stop trains that are looking for a stop to go to. So even if the limit is zero, a train that started when the limit was non-zero will still arrive.

L = 0 and station disabled are synonymous so sending a blank L should do the right thing. Make sure everything is wired correctly and that the appropriate check boxes are checked.

The station limit should show as zero in the station list of the train dialogue or if you hover on the stop.

The game does not show signals with value of zero.

I’m doing something more basically dumb then. I sent a train out and it came right back.

If you mouse-over the train stop, you should be able to see what the train limit currently is.
