I ran into the same problem a few months ago while trying to install the contents of a .rwp file into Rail Simulator. Believe it or not, this simple trick seemed to work: simply rename the file extension from .rwp to .zip, and then open the file using your default un-zipping utility (Winzip, etc.). Doing this allows you to extract the contents of the package, which you can then copy and paste into the appropriate location(s) within the Rail Simulator file structure. After doing this, just make sure to delete the blueprint files so that they get regenerated on startup, and start the game. The new content should be there.
Hope this helps
I renamed a .rwp to .zip and winzip objected but 7zip was ok.
installed to an RSC folder under ASSETS
Which blueprint file do you delete?????
