RiftRail currently relies on the train colliding with and destroying an internal collider entity to trigger teleport entry. If that impact damage is suppressed, the trigger never fires, so the train gets stuck on the collider instead.
At the moment I’m not planning to prioritize compatibility for this class of mods. Fixing it cleanly is not trivial, and I don’t want to add a heavier runtime solution for a niche compatibility case.
So if you want to solve this problem, you may need to continue using the version I provide separately. I will not merge this fix into the version released on the module platform in the future because its modification is a logically complex thing for me and has a lot of impact.
