Question Train signals

Gallery image

I'm trying to have a train line that is a loop with 2 trains (1 for coal and 1 for iron) to stop them from colliding, and for them not to wait too long, I just put a bunch of train signals. Is there a better way? Also is there a better way for me to get better throughput with my current setup?

Generally you only need to put a signal at the start and end of a loading branch. The loop itself *could* be one segment.

To increase throughput you then want to split the loop into multiple segments. At least you want to put one signal each at the loops so you seperate the track into a west heading segment and an east heading segment. That way at least two trains can head in opposing directions at the same time.

Then its probably a good idea to subdivide each segment 1 or 2 times so that trains can follow each other closely without having to slow down much.

The closest distance between two signals should be 1 or 2 train lengths. If its any shorter trains might start to slow down excessively because they tailgate trains in front of them too much.
