The Simple Passing Loop Test - FAILS

[paulz6]

The Simple Passing Loop Test.

The Test Route
A single line with a bi-directional passing loop in the middle.
The passing loop is not equidistant in the middle.
There are 4 1T 3 aspect control signals protecting the exits of the passing loop.
There are 2 junction signals on the approach to the passing loop.
There are 2 destination markers at each end of the single track line.
There are 2 destination markers on each line in the passing loop.

The Main Scenario Test
Place an AI train of equal priority at each end of the line and tell it to go to the other end of the line.

The Secondary Scenario Test
Place an AI train of equal priority at each end of the line and tell it to go to the other end of the line, this time helping the dispatcher by choosing which track in the passing loop each train should use on the way with a no stop instruction.

The Successful Test Result Requirement
Each AI train sets off simultaneously.
One of the AI trains should reach the passing loop first and come to a halt at the signal.
The second of the AI trains should enter the passing loop and proceed to its destination without stopping.
The first of the AI trains should then start and proceed to its destination once its signal as cleared.

The Actual RW Test Result
Scenario failed to load. !!!

Hi,

can you provide a screenshot of layout?

I can get it to run set one of the loops to up/down,leave the other one as both.Only used a portal at each end no other markers.Also used an extra signal on the up/down loop,half way along.

The problem here is that we are then route building around the AI sub-system to get it to work. When building a real world route, I don't want to add signals that shouldn't be there just to get the AI to work. I also want to set the track directionality as it should be in real life. It is clear that the AI sub-system needs a radical overhaul.

Indeed, but in the meantime any dodge is welcome.

I got some level of success by setting waypoints, and setting the service nearest to the passing loop with a stop at instruction. The other service I could set with a 1 - 20mph pass through (probably depends on the length of the loop). There are still some odd things that happen, such as AI drivers coming to a temporary stop at some signals even through it was on proceed or caution. Without restarting the scenario, other odd things could happen such as AI drivers coming to a halt at the back of the exit signals on entry to the loop.
It's still not what I would call satisfactory AI handling. I'm wondering that if the occasions where '!!!' is due to an AI train being in the way, that it could be made a warning rather than a hard error. Providing the AI drivers have enough IQ, the sim should be able to run with AI trains experiencing signal hold ups.

I too tried to create a revised passing loop test route after getting extra tips from Andi and others familiar with pathing issues. At first no matter how much I'd slice the railway into little triangle-joined sections, it would behave exactly the same and leave one train waiting at the entrance to the loop with the other stuck waiting in the loop track.

Then I got the bright idea to add in a portal and send the AI there. Boy, was that a BIG mistake. The whole route got corrupted such that I can't get scenarios to do anything now. Lesson learned: package your route as soon as you are ready to start messing with it.

And in the end I"m still just as stuck on getting this to work, much less figuring out why it works or doesn't. :bad-words:

Might I humbly suggest that a good idea could be to send the route and scenario to RSC support and ask them how it should be done or why it wont work no matter what you do. Unless more users do this what chance is there of them seeing what we think needs fixing.

John,

that does sound like a good idea. If I actually get a reply or a word from RS.com I'll see if I can do that.

Cheers,
