It would be awesome if the railsingle subassembly allows
- the slope of the ballast and the subballast to be set, becuase in reality, it is not flat and needs slope for drainage. Right now, I'm using genericpavementstructure as the subballast and connect that with a vertical link to the railsingle subassembly.
- varying the rail height because there are different types of rails with different heights. 1 or 2 inches can affect the earthwork calculation greatly for 1000+ length of track (I am currenlty using the vertical links to make up for the the rail height).
I pretty much don't use the ballast and subballast feature in the railsingle subassembly, unless I only need a quick and dirty estimate.
