Civil 3D used for designing railways

[Anonymous]

Can somebody tell me about thing in subject? Is there any company that
uses this software for railway design?
?

It works about as well as Land Desktop for rail design, maybe a little
better. Superelevation is still a really tricky thing to apply to a rail
section. For example, a rail profile is always top of low rail, so you will
probably need a different subassembly for left and right turns. None of the
stock subassemblies can model superelevation in rail sections. You could
draw one manually for the fully superelevated curves, but the transitions
would require a macro, and you would have a thousand regions in your
corridor. It can certainly be done with a bit of effort, but there aren't
any tools or subassemblies specifically designed to do it particularly well
or particularly easily. Also there are no rail-specific components like
turnouts and crossovers. InRail is still probably your best bet, but I
wouldn't be suprised if Autodesk comes out with some rail design tools at
some point down the road because the technology is certainly there.

If you are looking for someone to write a subassembly macro to help you with
this, contact me offline. I have a little experience in rail design & I
think it could be done with a bit of effort.

Thanks for answer

The problem is that here in Croatia we use different type of transition
curve, which is cubic parabola but not the same as one in civil 3d. I have
searched net for some information about that and asked our dealer. Havent
found positive answers at both locations. On internet, I have not found
anything more about civil 3d and rail than little stuff brochures. And
dealer company too does not have any experience with railway, only roads.
But they said that there could be some rail features in 2007.
Do you know if there is a way of adding different type of transition curve
in this version of civil 3d?

In my company we have another specialized software which i am planning to
study soon but it is much more complicated and user unfriendly compared to
any autodesk product.

Thanks in advance

James mentions on www.civil3d.com that there are some new spiral features in
2007. Perhaps someone who is allowed can chime in with some details.

Sorry for the non-answer.
