+Open Rails also supports a simpler way to define superelevation based on curve radius only, resulting
+in the same superelevation regardless of track speed. If a railroad uses this simplified method, they
+would provide a table of track curve radii and the superelevation used at that radius (usually also
+including a maximum speed for the curve). This table can then be provided to OR using the
+``ORTSTrackSuperElevation`` parameter in the .trk file::

 Each paired set of values must have an x and y value present. If it is desired
