Soon, there will be no more RSSLO track *in the middle off the grass*!!! I have tweak some xsec and without any other work, SemmeringBahn and Tauernbahn already have the enlarged gravel track bed. I have just to some tests on Tirol Austria, the lofted item is perfect on flat track. It's possible to lay gravel track bed portion of upto 5 Km in one time. I think I will place it on all the tracks.
Exemple on Tirol Austria Under work :
SemmeringBahn and Tauernbahn which already use the xsec are really great looking.
