foreign stations missing
The collection does not include stations in other countries, even though some of them are regularely operated by DB and available in its 'Fernverkehr' API.
Maybe we could fetch all of them from the DB API. But how do we make sure we cover all?
Possible idea: Call the API with every station ids between 8000000 and 10000000. 😁
The following script will walk through the captaintrain/stations data and filter all stations that DB can provide departures for. They also need to have a db_id.

const floor = require('floordate')
const fs = require('fs')
const hafas = require('db-hafas')
const pipe = require('multipipe')
const csv = require('csv-parse')
const filter = require('stream-filter')
const hour = 60 * 60 * 1000
const day = 24 * hour
const when = new Date(+floor(new Date(), 'day') + day + 10 * hour)
const isDBStation = (station, cb) => {
hafas.departures(+station.db_id, {when})
.then(() => cb(null, true), () => cb(null, false))
}
pipe(
fs.createReadStream('stations.csv'),
csv({delimiter: ';', columns: true}),
filter((station) => station.db_id.length > 0, {objectMode: true}),
filter.async(isDBStation, {objectMode: true})
)
Hey, i´ve a question: I´m looking for all stations of all cities in saxony for the last years (cause i want to look, how the connection of the cities has changed over the time). First: I found the data of DB Station&Service AG (https://data.deutschebahn.com/dataset/data-stationsdaten). Pretty good, but: These data doesnt include the sold - but still active - stations (for example Erzgebirgsbahn).
Do you know, where I can get all these data?
I made db-hafas-stations once, but it's a bit outdated, and I have never assessed if it contains all (or reasonably many rather) stations. It should contain all that bahn.de knows about though.
Also, I just wrote hafas-find-stations, but I haven't tried it on a large scale. You can test it if you want.
Other than that, OSM might be a good source, but again there's no guarantee that every station is in there.
