[openrailwaymap] Putting segments to route

Hi, is it allowed to create a relation Dresden - Leipzig, a relation Leipzig - SFS - Erfurt and a relation Erfurt - Fulda and a relation Fulda - Frankfurt (Süd) and then put all these relations in one master route? If yes, some tools could profit from this to show big routes constructed out of pieces. And the small pieces can be used in many routes. When constructing an IC Dresden - Leipzig - Hannover - Köln, the first piece Dresden - Leipzig already exists and can be used for it. If it is forbidden, how long does one come in prison if he creates such relations? Greets Peter
