I am curious if anyone has manipulated any of the rail subassemblies to have greater control over the characteristics of the ballast and subballast sections. I have attached an image that describes the three things that I am looking to do to meet the local railroad standards, specifically:
- It would be nice to have a width target for the top of ballast to extend the shoulder in areas where walkways should be shown.
- It would also be great to be able to have a width target for the subballast in areas where you have gradual subballast width changes such as an access road dropping in width or the need for more subballast under an extended walkway section.
- Lastly, it would be nice to have a numerical definition or a width target for the crown of subballast. Our local RR likes for the subballast to crown outside of the tie, leading to an asymmetric subballast section to prevent stress on the ties as the ballast settles over time.
If anyone has tried this, or found some other way to perform these function I would love to know. Currently my firm resorts to using the roadway tools to make a subballast corridor with widths targets, and then a separate rail/ballast/tie custom "subassembly from a polyline" and general links to displays those features. It would be more convenient to control all of these aspects within 1 corridor, especially with some of the enhancements that have come with the rail package in 2020.
It would be nice to have these features on the single rail, left rail, and right rail subassemblies. The interior rail subassembly already has target widths for subballast I believe.
EDIT: It would also be nice to slope all of the subballast one direction.
