Here are some screenshots from my own Bahn layouts to give you an idea what Bahn looks like before downloading a copy.

A Fictitious LRT system. (Grey track backgrounds are used either for tunnels or tracks on road)

Small station with steam special and DMU, Note the bus.

Minfordd station on the Ffestiniog Railway in Wales.

Due to problems with the Bahn colour palette and conversion to GIF files, the colours are slightly different to those in the program. Also these screenshots are only from 3.40 but 3.58 is very similar.
