You may find the following of some assistance:

Bavarian Railway information: http://www.kbaystb.de/

John Oxlade's excellent Bavarian information site: http://www.worldrailfans.info/Articles/Europe/GBavBL1.shtml

A generic site listing a mix of plans: http://www.bfp.de.vu/

A Dutch site with many German plans: http://www.sporenplan.nl/index.html

There are many others. Decide a region and then you have a chance of making sense of it all.

There are also many books dedicated to the subject of track plans; when you decide on a region, some specific recommends are possible.
