I'm afraid at the moment RailClone does not have a mode that will deform the segments to create the skew and fan-like pattern required to reproduce this style. This would require a variable deformation on the Y axis, which is not currently possible.
The closest I can get is to create the RailClone object with the segments upright and then apply a modifier such as an FFD or Taper to deform the whole style. This has the drawback of remove instancing so may not the the most efficient approach in the event of heavy geometry. For the future we are investigating creating a generator that is able to use two different splines to define different paths for the top and bottom of the array that should help create styles like this, but there are many technical challenges we must resolve first.
I hope this helps, please let me know if you have further questions.
