The german railway site db.de is only useful to search for train connections, from a traveller's point of view.

This style removes all the disturbing junk and ads promoting Deutsche Bahn.
Only the search box is shown and you may choose between a nice background image or a neutral background.

This does *not* modify bahn.de, instead use db.de to find train connections.
