This is a very cool model, and will be a much needed addition to the game! Thanks for building this fine looking model!

You can do it exactly like you would in MSTS. Put the Bogies groups as 1st level child groups to the main group, then add the wheels as children to the bogies. Rename everything to RW standards, either in the group names themselves or by using the RS custom fields in 3DC.
You don't need to do anything else than that, just name and group the parts correctly and it will work fine in RW.
So the hierarchy could look like this:
1_0032_engine
- 2_0128_engine
- [other groups]
- 1_0256_bo01
- - 1_0128_bo01wh01
- - 1_0128_bo01wh02
- - 1_0128_bo01wh03
- - 1_0032_bo-clutter (just to illustrate that you can add more groups as children to the bogies, and they will become part of them in the sim as far as animations etc. are concerned.)
The only other thing to watch out for is that the pivot offset values in the BIN files (bogies BINs and wagon/engine BINs) must be identical to the actual pivot (offsets) in the shape file. So, for example, if the two wheel groups on a two-axle truck are -0.9205m and +1.1120m Z-offset from the truck pivot, then these are the values you should enter in the bogies blueprint.
