As I have seen now, Railcraft needs a house-cleaning. Use Intellij magic to clean up those imports, and add javadocs for every public/protected method, following the google java style?

More, I think applying a plugin called "checkstyle" just like that one in Buildcraft and Sponge would improve the style.

Oh come on, its not that bad.
