Interesting junction/turnout-related observation in TS2009 SP4

In this post, I use junction to refer to both junctions and turnouts, as they are the same thing.

Hi Trainzers,

Whilst I was running a driver session on my custom route earlier today, my train came to a red signal. The interesting part of this is that the junction lever for the junction after it was on the left-hand side of the track, and the train could not change it.

I've found that if you have the junction lever on the right of the junction (for splitting junctions) and on the left for joining junctions, the train could change it without issue.

See the following diagrams (taken from Surveyor, click the images for full-sized versions):




In the first diagram, the train cannot pass the junction, as the lever is on the left. The second one can though as the lever is on the right of the junction.

For joining (merging) junctions, it's a mirror image of the above.

This may sound trivial, but it does seem to make quite a bit of difference in AI situations.

This is likely to apply to most versions of Trainz, although I've only been able to test it in TS2009 SP4.

On my TS12 version, I am able to place the switch on both sides without incident for both human and AI trainz. This could be either an isolated incident for you, or something in the TS2009/SP4. I hope our fellow Trainzers will also weigh in on this to see where the heart of this quirk lies.

I'm hoping they will as well, as it does seem a bit odd if it's just happening to me.

since the tracks are so very close together, are you certain it wasnt on the other track all along? i dont see or cant think of any reason it would matter what side the lever is on. it is just a representation of an object on the track graph. it doesnt need to be visibly on any side at all.

That's what baffled me - it is on the correct track.

I routinely rotate levers from their default position to better suit prototype practice for specific locations. I have never had a lever issue that I could ascribe to which side of the track the lever was on.

A couple of observations though about that specific set-up. I would be more inclined to suspect one of these three issues:

1. A short single-iteration length of track leaving a junction. Add some more track and see if the problem goes. This will be compounded by...

2. No end-of-track marker.

3. The lever looks to be in the wrong place. Levers should be located just before the diverging spline point, not in the center of it. The fact that levers default to the wrong place doesn't help!

The different experience with facing and trailing junctions is possibly because neither (1) nor (2) are relevant if approaching the lever from the trailing side...

I will have a further look tomorrow. If you are wondering why I have track like that, it's to prevent a different issue (train not leaving station)

I've used that trick a couple of times myself, but you still want that second spline iteration and an EOT marker! There are 'invisible' versions of everything you need which mask the thing almost entirely...

Hi guys.
I am not sure if this has bearing on the subject and pse excuse me if I am talking in the wind, but I have noticed from experience and also in several threads that when in track mode and making changes in surveyor there are marked differences in effects to track changes when using advanced or just straight option. When tracks and industries etc are added into existing tracks without using advanced option like 'add spline point' or 'delete spline point' there are always problems like missing junction levers etc after wards, which are only noticed when back in driver.
