I think this will be a very interesting idea. Especially for the fact that it is not unusual to see railways (monorail, metrorail, etc) be suspended over the roadway.
As a workaround, one can create a component based road and add decoration to visualize the rail details. With this approach, bridges can then be modeled as shown in the example created below. It should be pointed out though that the geometry of the component road as well as the behavior at intersections will be based on design roads.
Very good points. For the sale of clarity, how are you modeling the existing rail lines? Does the modeling of such rail projects also involve multiple alignments, switch yards etc?
Also, regarding your last sentence, are you modeling new bridges on new roads that are crossing over existing rail lines or are you referring to the need to model new rail bridges along existing rail lines that are somehow crossing over the new roads?
We try not to model existing rail lines, we are simply using the rails that come in with model builder. If we do have to model an,y we just use the simple draw rail command.
Sorry, I got my terms the wrong way round! We need new bridges along existing rail lines that cross new roads. Currently this is very difficult to achieve.
Thanks for the clarifications. The existing rail lines that come with Model Builder, as well as those created using the draw rail command are not at a level of detailed design (in terms of alignment geometry, cants etc). On your rail projects, would you later be recreating these in say Civil3D during detailed design?
For the earlier design stages, what if we provided a way to convert the rail line into an equivalent component road such that you can leverage the bridge modeling capabilities as shown in my earlier response?
@ara.ashikian do you think that a deeper development of this will be taken into consideration? I am following some projects in which the rail are completely on a bridge, I will for sure follow your example!
Absolutely @ara.ashikian!! Thank you for your feedback.
When I ask for deeper development, basically I was thinking to the possibility to achieve the same thing we can do with the road design, obviously translated into railway possibilities.
To be more clear, I was thinking in particular about bridges. The same issue that you explained in the previous topic.
I am working around Project Kameleon. And maybe the possibility to interact with revit as well.
