Odd car behavior

[jrs_diesel]

Greetings all

I've enjoyed MSTS over the years, but have recently discovered Open Rails, which is amazing!

I've been adding to my rolling stock (freight) and added a flat car that has a quirk. Not sure if this question belongs in the MSTS forum or not.

This particular flat car is a model by Robert Murphy, it's a JTTX with a damaged tank car on it. The trucks are removed from the tank and are secured down behind the tank on the flat car. It looks great when sitting still, but when I get the train rolling, the wheels on the secured trucks start to revolve around the car . Doesn't affect it from rolling, just looks very strange. See screenshots.

Is there any way I can fix this?

It's fixed!

I was able to get in touch with Robert Murphy, who created this particular car. With his guidance, I was able to change a parameter in the S file for this car. So now the extra axles no longer "orbit" as they did before.

Thank you Robert!

I have this car as well, but haven't used it in awhile. Would you be able to post the parameter that needs to be changed?
Thanks,

Jim

Sure thing Jim.

You'll have to edit the shape file, which is the one with the .s extension. In the case of this car, it is named JTTX_Tank.s

Shape files I learned are compressed, so you can't edit them easily like you can with a .eng or .wag file. You'll have to use a utility to first decompress the file, edit it and save, then compress it. It also has to be saved as a unicode text file (Wordpad can do this). I used a utility called Shape File Manager.

Here's the link to the tutorial for it, there's a download link for it too: http://msts.steam4me.net/utilities/s...e_manager.html

Make a backup copy of that S file before you start, really easy to screw up the file when editing it. After I decompressed the file, I hit the option to EDIT .S. Once Wordpad opens, hit CTRL F, and search for WHEELSETS. You should see the same thing like in my screenshot. You'll just have to delete the WHEEL from WHEELSETS, so it will read just SETS. Hit the save button, and exit Wordpad. Compress the file. Load up Open Rails and test it. The extra wheels on the flat car should now stay put

Thanks for posting this fix. It worked perfectly. Thanks also to Robert Murphy looking into this quickly and coming up with the solution.
