How do I extend the rails?

Select the Bézier curve Rail_BezierCurve, go to Edit Mode, E to extrude a control point, then move the handles as needed.
The track (Array + Curve) updates automatically to the new length.

Can I remove or tweak the stone path?

Yes. You can delete the stone path if you don’t need it, or increase its Subdivision level for more detail (e.g., 4–5).
⚠️ Higher subdivision uses significantly more memory. Consider lower Viewport levels than Render.

How do I use it with the Asset Browser/Manager?

You can append from the .blend (File → Append) or add the file/folder to your Asset Browser/Manager.
After placing the asset, press F3 → search “Make Instances Real” to convert instances into editable objects.

(Pro variant) How do I adjust the catenary?

• Edit the Bézier curve Rail_BézierCurve to follow your track.

• Typical EU spacing: 40m

Units & scale
