Lack of thought about EIT (Enhanced Interlocking Tower)

Just can't seem to get the interlocking thing right. I've built a small diagram: single track, two passing places which replicates a railway layout. The whole thing should work endlessly, always going from A to B and back and then starting again. Attached is also the test route.

I've created mission codes, paths and all the things needed as you can see in the picture. The idea is that the train takes its route from A to B and checks whether the path before it is clear. If it's clear, it always uses the main line; that's how I set it up for the sidings. But that's where it starts: sometimes it uses the siding, sometimes the main line, even though everything is clear. Now the next problem arises: it activates a path into a siding and then both paths out of the siding. But it can't get out because it always takes the wrong path. Now the endless story only works if I always intervene and deactivate the wrong path. See below: on the left siding, both exits are activated, even though only the left one should be. But the right track is actually the main line.

The next step would be for two trains to do this at the same time. So, one train waits at a siding, and the oncoming train takes the opposite track. That doesn't work either, because the first train blocks the switch that the second train needs to take. Here, I have to manually deactivate the request from the first train, then the second train can enter the siding. Why is that? See below. Initially, both exits are reactivated, even though it should only affect the left track. Because the right track is also activated, the lower train can't drive into the siding. So I have to manually deactivate it again. Here, both paths for the upper train are activated, because it activated the paths first, and the lower train later and now waits in front of it. Will the situation continue as it is or will ILT come up with the idea that it must first let the second train through in order to continue with the first?

Your driver setup rule comes up blank/faulty. <kuid2:438196:100023:4> is unknown.
You need the use of the green EIT triggers to shorten the distance the tower can see a train. This should reduce the control of the exit paths.

Thank you Stagecoach, the tip about the green path trigger helped me, now it runs with one train in a continuous loop. How can I get the train to stay on the main line instead of using the siding? It seems as if the train is traveling along the tracks as they were laid? If he goes north he takes Siding, if he goes south he takes Main. Can this be solved with priorities?

As soon as 2 trains are running there is a standoff again. The initial situation was that the lower train first went along the siding path and then turned around. Meanwhile, the second train arrived and took the main line, since the siding path was still blocked by the first train. So far, so good. Now, however, the second train has first access to the signal for turning and the corresponding switch. The first train, however, needs access to pass the second train on the siding.

<kuid2:438196:100023:4> Rural Japan - Model Trainz Region is just the region. I think it can be ignored
<kuid:-25:1534> is the buildin Driver Setup Rule which is on my end not faulty. 2 of 3 Driver got this commands. I work here in 128486

The end sections need the block set-up like you used on the passing areas. EIT can not see a train in the end section, unlike signals, it needs to check the block to see if it is empty. This would also apply to the single track section.
