I've used this API for one of my projects, but Marudor just made his HAFAS API online.
https://docs.marudor.de/#tag/HAFAS-V1
It has many more features and doesen't rely on some web scraping.
Just use some POST-Requests.

Hi there,

great package...it's really helpful.

Do you have any idea how I can do many requests at once?

thanks

Hi,
I've got small question - I want to use this integration with HomeAssistant, but I have problems using it in Polish connections (Polish trains are visible on bahn.de).

I want to query for i.e. such connection:
https://reiseauskunft.bahn.de/bin/query.exe/dn?ld=43166&protocol=https:&seqnr=1&ident=i3.012020166.1659559405&rt=1&OK#hfsseq2|i3.012020166.1659559405
(starting point is Mysłowice and target is Katowice) and it works for "Myslowice"

I try to use it for "Mikołów" (Mikolow) and then there's no results at all, although there should be some:

I'm able to get data from:

import schiene
s = schiene.Schiene()
s.stations('Mikolow')

but not for

s.connections('Mikolow', 'Katowice')

Thanks for any help!

Not working:

>>> s.connections('Hamburg Burgwedel', 'Hamburg-Eidelstedt')
[]

Working:

>>> s.connections('Hamburg Burgwedel', 'Hamburg-Eidelstedt Zentrum')
[{'details': '...snipped..., 'canceled': False}]

"Hamburg-Eidelstedt" and "Hamburg-Eidelstedt Zentrum" are different stations and I want to have the first one as my target stations but it does not work. Is there something I can do? I am actually using homeassistent but I tried this explicitly in a python shell to pinpoint the issue.

Instead of marking a train as cancelled there are details which state that the train is cancelled, see screenshot.
Is that something that could be caught by the client? Not sure how, maybe report the comment so others (i.e. the home
assistant integration) could filter based on that? Not sure if the text is always the same though.

I am playing with this project and sometimes i get an empty list from the connections() function.

Is this due to requesting too often or due to some other error? Is there a specific limit?

Somehow it's working now. :)

Hello,

Use HAFAS instead off scraping. It should be more reliable and approved by Home Assistant as proper integration again.

https://github.com/FahrplanDatenGarten/pyhafas

I am happy to try and help to change it. Do you see any issue in using pyhafas?
I am now trying to add it into schiene. If you can give me any hints, I'd be very happy.

Hi, your setup.py seems to miss lxml as a required library (it is not automatically installed with BeautifulSoup4). Not a big deal, but you should probably add it (or use "html.parser", which afaik is always available).

If there are more than 24 hours between start and arrival the "time" value is not accurate. It does not take day changes into account.

The Connection today from Stuttgart HBf to Ulm HBf at 10:51 was canceled (see. screenshot below), but connection is reported on time from schiene:

s.connections('Stuttgart HBf', 'Ulm HBf', datetime(2024, 4, 25, 10, 50, 0, 0))
[

"details": "https://mobile.bahn.de/bin/mobil/query.exe/dox?ld=4357&protocol=https:&n=1&i=dt.01855957.1714033988&rt=1&use_realtime_filter=1&co=C0-0&vca&HWAI=CONNECTION$C0-0!details=opened!detailsVerbund=opened!&",

What do you think? It would need registration by everyone who whats to use it, but we would get rid of the html paresing. In terms of stability and future proof ness it would get a lot better I think. For Home-Assistant I think it's the right way.

i use this package with home-assistant.

Since i upgraded i have following error:

"/usr/local/lib/python3.5/dist-packages/homeassistant/components/sensor/deutsche_bahn.py", line 82, in update
"/usr/local/lib/python3.5/dist-packages/homeassistant/components/sensor/deutsche_bahn.py", line 105, in update

Here is the same error reported what i had a couple times in log:

home-assistant/core#21118

self.data.update self.only_direct

Could you please fix it? :-)

Thanks a lot!

Hi, the code crashes when trying to query the next train to Vienna. The 'Wien Hbf' is a valid name for the station as returned by s.stations('Wien')

s.connections('München','Wien Hbf')

    delay_departure_raw = soup.find('div', class_="routeStart").find('span', class_=["delay", "delayOnTime"])
AttributeError: 'NoneType' object has no attribute 'find'

I tried using Schiene as a home assistant sensor but after the first try—it did work for a brief amount of time—, the underlying library stopped working.

The problematic connection for me has been from Leverkusen Mitte to Köln Hansaring

Hey

I'm experimenting with your API and in general it is working. However when I make a

import schiene
data = schiene.Schiene()
res = data.connections('start', 'goal')

call, it returns a list of the next four trains for this connection. I think res[0] should be the next connection, however I usually see tat res[0] is the one after the next, and the next connecton is not
pulled in at all.

Hi! I'm working with the VBB public transport API, which is based on HAFAS. I wrote a JavaScript API client for it.

Deutsche Bahn uses HAFAS as well, so consider using the API instead of parsing a "steaming pile" of HTML. ;)

I just started getting this error-message when trying get a connection.
Other destinations seem to work (e.g. 'Mannheim HbF' to 'Stuttgart HbF').
Is there anything I can check?
