This is a very weird bug and seems to be new.

When I was trying out the new tilted curve track pieces, I noticed that they were disappearing when going at high speeds on them.

HOWEVER, the track pieces only disappear if you run the Long X12 at full speed over them. I tried all the other trains to make sure it wasn't just the Long X12 but I can confirm that the Long X12 is the only one that's causing this.

Also, it's NOT just the tilted curves that are disappearing. I also drove the Long X12 at full speed over the normal curve pieces and they were also disappearing.

Reproduction Steps:
- Set up a simple oval layout. I recommend using 2 to 3 4096 straight tracks to build up speed and 2 90 degree curves or 8 22.5 degree curves to make a 180 to show them disappearing.
- Grab the Long X12 and bring it up to max speed.
- Driving the Long X12 over the curve pieces should show at least one curve pieces disappearing. (It doesn't always happen so you may need to do this a couple of tries for it to happen).

Extra Notes:
- Singleplayer
- x64 Chromium Beta
- No Script Errors show up when this happens.

I also did a trouble shooting session to see if it was a conflicting addon but I can confirm that there are zero addons involved in this. I must be a bug within either the SW X12, the SW Model Pack, or possibly all SW trains if they have the same issue yet harder to come across because they go slower.

I'm assuming that the reason why the Long X12 is the only one causing this has to do with it's speed, since it is the fastest SW train in the collection.

Goodie!

And that stability trick, I did not know that. But that'll definitely be useful in the future.

No worries! I 100% understand your reason.

Unfortunate as it is that this didn't get to see the light of day, I am happy that you saw at least a little potential for it. Either way it was worth a shot.

Thank you for the correction. Much love!

That's surprising, but I can understand and respect the decision.

Thank you for the response.

A separate addon that is SW School Buses. Contains both Long Nose and Flat Nose School Buses. These could have functional doors, flashing yellow and red lights, the stop sign on the side, and the walk guard.

I'm glad I was correct.

I figured this wasn't gonna be fixed due to complexity but it was worth getting out there regardless just in case any body else try's to do this.

Thank you for your time.

I noticed something weird with all the Articulated Vehicles. Whenever I weld any props on the Articulated sections and then re-spawn it with the duplicator tool, the welded props don't show up on them.

Affected Vehicles:
- SW Articulated Bus
- SW Bi-Articulated Bus
- SW Old Articulated Bus
- SW Articulated Tram
- SW Short X12
- SW Long X12
- SW G15 Wuppertal Suspension Train

What is happening:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3447414419
I'm using the Articulated Bus as an example. In the screenshot are four articulated buses. The two buses on the left are spawned from the spawn menu and the two buses on the right are copies of the left ones that were spawned from the duplicator tool.

The top left bus has a barrel welded to the front half. I then re-spawned that bus with the duplicator tool which is the one on the top right. You see it retains the barrel that was welded to the front.

The bottom left bus has a barrel welded to the back half. I then re-spawned that bus with the duplicator tool which is the one on the bottom right. Notice how that re-spawned copy doesn't have the barrel on the back half. That is where the issue comes into play.

Theory:
My theory as to why this is happening must be because of how the Articulated vehicles sections load in. Each section seems to be classified as it's own vehicle/entity, but it can only be spawned in if the first section is spawned in first. For example, if I spawn either the X12 or the Bi-Articulated Bus, each section loads in like stages. The front loads in first, then the middle, and lastly the back. But the first section is the main vehicle itself. If I were to save it as a Dupe, only the front section show's up in the thumbnail, leaving the other two sections non-existent. It must be because the front section is required to be spawned in first in order to allow the other two sections to load in as well. However even if each section is connected, they act is if they're not, hence why they don't show up in a Dupe thumbnail. So any prop that's attached to the front section is going to show up in the Dupe and when spawned in. But if I were the save it with props attached to the sections instead, they won't show up in the saved Dupe and won't show up when spawned in, therefore leaving those props non-existent, too. Again this is just a theory so I'm probably wrong about this whole thing.

Tilted Curve Tracks are very common on high speed train lines, as they allow trains to go through curves at higher speeds without the risk of tipping over.

Since all SW Trains can go at very fast speeds, I think tilted curve track pieces could be a good use if someone wanted to make their own high speed train layout.

To show you what I mean, here are some screenshots.

Here is a titled curve I put together using the track assembly tool and a collision re-sizer.

The build looks a bit funky because the outside curve is acting as the elevated rail.

There's also this one train map I go on and I think it's a really good example to show because it features Tilted Curves in the layout. Here are some screenshots to show you what I mean.

I believe this map was made by (FC&N) Magnum MacKivler.

Tilted Curve Pieces:
- 22.5° Tilted Curve
- 45° Tilted Curve
- 90° Tilted Curve

Tilted Curve Transition Pieces:
- 1024 Right Elevated Straight Track
- 1024 Left Elevated Straight Track
- 2048 Right Elevated Straight Track
- 2048 Left Elevated Straight Track

Note: The Tilted Curve Transition Pieces are the Track Pieces that transition from normal level track and into the Tilted Curves, since one side of the Track goes from normal level and slightly elevates to the same level as the Tilted Curves.

I fully understand.

To be honest, I did have very low hopes for this idea since I knew that there would some issues and counter arguments with it that I wasn't fully aware of.

But it is nice to get a second answer from someone else so that I know if it'll work or not.

Thank you for the response.
