Add some documentation about the hdrf

In general: please indent the # (hash) for the comments.

I don't know if its a good approach to polish this source at this moment. I am considering a rewrite with generalises the parsing based on the documentation.

[timetable2014]

I try to give so more insights to the documentation.

[skinkie]

Guessing what the meaning could be was not the issue ;) But I am under the impression that the Haltestellennummer is actually not bahnhof here, but a mask.

[timetable2014]

yes, it's a mask. the haltestellennummer starts with the UIC - Code. If you have a Haltestellennummer which is not in the zeitvs, you have to decrease the number of the haltestellennummer since you have a match in the list

[skinkie]

Could you maybe tell me if there are any other situations where this 'mask' situation applies? I would like to add the timezone to the GTFS stops.txt.

[timetable2014]

I think for zeitvs there is no second mask

1100000 0000000 means, that all Station starting with 11 uses the same timezone as 00000000

[skinkie]

I was more thinking in terms of the format itself, situation where a join on haltestellennummer = bahnhof doesn't directly apply but the mask does

[timetable2014]

I didn't understand the question. Are you looking for situations where this masking works in other files?

[skinkie]

Exactly.

[timetable2014]

no, the masking is just in zeitvs. sometimes @@@@@@ is used indicating, that all stations have the same properties.
