Hello All:

In addition to Bavariam Saxony is a region in Germany which also has quaint nebenbahn and rolling stock.  This area east of the divide of the DB/DR during Era 3/4 ran steam until the late 1970's and maintained passenger and freight travel on the rail later than the DB.   There is a good archive of various stations here:

Comparing the Saxon stations against the Bavarian stations:  My impression is the Bavarian's prefer 3 tracks or more in their stations while the Saxons would make due with 2 tracks.  The Bavarian's prefer to use the the center track for the mainline and the track close to the station was for loading.  Both used the outer track as the run-around track.  The Archatecture of Saxony is easily identified and the companies Auhagen and Busch produce these. 

Most of the Bavarian nebenbahn were funded by the local comunities.  The end station would typically be a town with  the funds to build the rail structure.  If the Towns provided the funds,  the railroad had the right to buid the line. The Bavarian railroad used predefined layouts in order to safe time and money during development.  In Saxony,  each line had to be approved by the state.  These Saxon lines tended to be introcuded more for financial incentive to move industry into the remote regions of the state.  It the line did not look financial viable - the line might be built as a narrow gauge line.  The landscape of Saxony did not contribute well to standard stations due the twists and turns of the valleys.  Each station is unique.

My impression is the Prussians considered the Railroad as a financial and cultural incentive to unify Germany.  The Prussians built a number of uneconomic nebenbahn with very small stations in an attempt to nit the country together.  I am not familiar with the Prussian Station Layout.
