In short, the BP editor is where you hook your shape files, sound files, or whatever files you are trying to get into the game, to a Blueprint. This Blueprint contains information on what the name of your shape file is, where it is located (path), name visible in the game, does it have Child objects, and so on. Once you export the BP, it becomes a .bin file in Railworks, which is just an encoded .xml file. Each different type of Blueprint can accomplish a different purpose.
It should be noted that the Asset Editor does the same thing as the Blueprint Editor, save that the BP editor cannot preview shape files that you are working on. Also, the BP editor can run and export while the Railworks game itself is running. The Asset Editor, while able to run while the game is running, cannot Preview during a game session.
