This is a crude hack to bring this yarn asset up to build 3.1 and eliminate the '2dm hop' between splines and fixed assets.
It remains the sole property of madeline usher and is subject to her original license terms.
A kazillion roads have already been created for Trainz but, nevertheless, none of them seem to meet everyone's needs. So I've created Yet Another Road Network -- a set of models mostly suited for modeling U.S. roads. These probably won't meet everyone's needs either, but hopefully some people will find them useful. :p
This particular model is a spline of four-lane road with no sidewalk, with a shoulder, and divided by a central barrier.
See the included naming-conventions.txt file for information about the attributes encoded in the asset's name.
