I was browsing around in the TRS2009 TrainzDev pages reading some information on the new "stitched" track and I noticed the following tags are to be supported:
 
mesh-length 0.0
adjust-height-to-ground-threshold -3.402823466e+38
adjust-height-to-ground-offset 0.0
adjust-cross-section-to-ground 1
use-superelevation 0
mesh-table
{
}
track-lod-tree
{
}
 
Note the use-superelevation tag. Sure looks like we are finally going to get it.
