Could anyone please explain the chain ability to me? I've read that they give double production when connected to both main buildings, the left kne and the right one, does it mean it has to be touched by the two of them?
In this case you can only have one track that touches both of them, if you add more tracks they will touch each other and only the far left track will touch the left building and the far right track will touch the right building.
Or does it mean that as long as the tracks, all together, are connected to both buildings they give they bonuses to both buildings, meaning for example one FP to the left building and one FP to the right one.
I'd appreciate it if you could explain the whole chain concept in details. Thank you.
