@Hrw:
Ok i will change the description.
Currently you must be online. I really don't know how to use offline data.

@All:
I will release version 0.0.4 tonight with working details page.
After that my todo is cleaning the code and seperate the parsing code and display code to support different databackends. I internally keep a list of possible backends (like mobil.rmv.de and other) to support a more localized display of trains.
