A shallow fill spline made of brown dirt, but with no endcaps for better alignment to objects such as bridge abutments.
For use under track (align the spline points with the spline points of the track).
This can also be used as a road if no track is used.
Fits narrow gauge track.
Textures courtesy of CGTextures.
A little more desaturated than the brown dirt version to better match some of the brown dirt ground textures out there.
Revision 1: added seasonal support.
