Würzburg sits on the Main River, so a Maintal run from Aschaffenburg should have been to Würzburg via Miltenberg. The last time i was in Fulda was on the Frankfurt am Main run to Braunschweig, which city sits on the line from Hannover to Berlin ... The last time i stopped in Kassel, i was on my way to Göttingen ... The last time i was in Siegen i was on my way to Koblenz from Giessen ? Giessen is on the line from Frankfurt ( Main ) to Marburg ( Lahn ) and .... Kassel. And that just leaves DTG connecting Achaffenburg to Frankfurt ( after Mainz to Frankfurt . )
Depends on when the routes are set. Msb then is different from msb now. Also to mention mergers aren't possible yet
Kassel-Wurzburg is one of the most broken routes I own. Before you even think of extending the route, DTG would first have to fix a LOT of things. Burgsinn station and many of the freight sidings have huge sections of missing OHLE, and the "inverted tracks" bug is everywhere. Then you have sections of bridge that suddenly pop-in or vanish under your train at many points. Not to mention the completely random LZB alerts you get for absolutely no reason.
