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 six-lane road with no sidewalk, with a shoulder, and divided by a central barrier. Note that the outermost lanes are not divided by painted lines -- this road is really intended to be used at exits where the outermost lanes are the lanes that are either exiting or merging. Use with 'YARN ExitA 4L DL3 -Si +Sh' and 'YARN ExitB 4L DL3 -Si +Sh'.
See the included naming-conventions.txt file for information about the attributes encoded in the asset's name.
