Floating train on steel bridge TS09-50m-001

[belgian46]

Hello everybody,

I have placed a steel bridge TS09-50m-001 into my route. This bridge contains no pylons.
During my tests I saw, when the train was on the bridge, it was leaving the track and even started to float into the air .

Here is a screenshot

Does anyone have a raison for this phenomenon?

Thank you

Best regards

Interesting. Tume's bridge is actually defined as a track object not a kind bridge so I'd expect it to behave like a track spline which will deform like that depending on shape of track attaching to the end points. But I don't know why the visible mesh isn't deforming to match the track path. It's like an invisilbe track spline is laid across a scenery object - you'd get exactly that effect. But that's not how the config is set up - at least as far as I could see. I didn't think you could define the track part separate from the rest of the visible mesh unless you used kind scenery with track or a derivative or kind bridge. [EDIT - The length tag in the config is 50m that's why. Trainz renders the track using straight line segments with lengths based on the length specfied in the config. But the track path the models actually follow is based on the mathematical spline definition of the track not the rendered mesh.]

Back to your problem. To fix it I'd lay the bridge as a single length and use the straighten tool on it. That will force the track path to run as a straight line between the end points making it conform to the visible mesh.

Hello Bob Pearson,

Thank you for your reply. I will try your advice and look where it takes me.

Meanwhile I also tried another bridge - Iron girder bridge which contains a pylon at the beginning and end of the track.

This Iron girder bridge was placed on the exact same place as the steel bridge TS09-50m-001. Placed the bridge and while placing, I saw the pylons.

Then I saved the route and I saw that the pylons were not visible anymore.

Here is the picture

I first thought this could be related to the fact that the bridge is placed between Hp concrete track. But that shouldn't be an issue. I tested it out.

So another weird thing.

Has anyone had this issue before? If yes what solution did you use.

ps. I let a train+wagon run over the Iron girder bridge and in this case the train followed the track and didn't start to float.



Thank you
