Train signals by default can be used to output a signal to the Circuit network depending on it's state. Fairly straight forward. However the issue is that when a Train Signal is unattached from a rail, it doesn't output a signal at all. This is actually contrary to the animated graphic of it cycling...

So I'm gonna lay down an idea. When landfill was intially introduced, there was a bug where you could fill in 4 tiles instead of just 1 with landfill. Which made things a lot easier to accomplish with filling in water. However, the recipe was never changed all too much when it was updated to fix the...

I've been working with rail signals with wire and discovered an odd bug in the signal logic when they aren't attached to a track. This applies to both the regular and chain signals. When they aren't attached or placed in an invalid spot, they flash Green -> Yellow -> Red -> Green. However with them ...

With the ability to add the train signal to the circuit network, it's really helpful to make crossing gate and control how the trains react based on logic. However I've noticed a strange issue when connect a flashing signal up to the circuit network, it continues to out put a green signal (or red if...

Since everyone here is talking about fluids...
I'm surprised that the train tutorial doesn't touch the Fluid Train Car, but does use the transport car, and I remember I was confused when I first built a fluid car on how to use it!
