Regarding downloads, there are several ways to get the OSM data.  From
smallest area to largest.
- download a bounding box from josm / export tab from osm.org
- download a bounding box from XAPI
- download an extract from an extract publisher
- build a local db from planet.

If you have a specific bounding box or bounding polygon in mind, I may
be able to run an extract for you.

Rendering transit routes is going to be a specialty project or side
project.  I wouldn't expect too see it on the main OSM site, unless it
is global in scope and really slick.  OpenCycleMap does similar
rendering but does not have the complication of frequent changes or
the need to distinguish many routes over one small section of road.

Here is a neat transit line map.
It comes from here, but I don't know who did this work, how often it
is updated and if it covers Germany only.
