Description
OS: [Windows 10]
Version: [0.3.1]
Commit/Build: [e.g.d01dcea]
If you have two trains going through helixes that are tangent to each other, they will both stop, which can cause other trains to run into them and crash.
Steps to reproduce:
- Build two helixes next to each other with the mini-roller coaster using automobiles for the car type
- Have them spaced out in such a way that they go through at exact the same time.
- They will suddenly slow or stop when next to each other.

Research direction
Start by loading the provided “Crashing Helix Mini Roller Coaster” or “Alcatraz” save and reproducing the two adjacent tangent helixes with automobile cars on Windows 10 and version 0.3.1. Trace the coaster and train simulation behavior when both helixes are traversed simultaneously; done means the trains no longer unexpectedly slow or stop, and subsequent trains do not crash into them.
