Describe the bug
Track models do not render transparency

How to reproduce
Steps to reproduce the unwanted behavior:

1. Install a custom track model with full transparency (eg ballast edges for blending)
2. Boot game on latest 1.16.5 IR Release
3. Place track and observe its beautiful lack of transparency

Expected behavior
On 1.12.2 track models fully support transparency. 1.16.5 should behave the same
