I’ve been trying to get rid of it for hours now, trial and error, reading devforum posts on similar topics, but I simply cannot get it fully resolved. This especially happens at higher speeds. If you have any idea what to tweak to get rid of this, please let me know!
Below is a video demonstration and a picture of the guider system (underground):
Yeah this is the issue with systems like this, even if you add clamps both above and under the rails, its still gonna glitch somehow; the solution to this is running cFrame trains which never derail, but can be complicated to set up ( how i do it is i run a physics train just like your system, but i run it at speeds low enough that it doesnt derail, and it spawns the nodes)
There’s actually a useful video made for it, and if you’re interested in the train aspects itself then
