	&stacjaOd=5100042
	&stacjaDo=5100136
	&typSkladu=ED161

dataWyjazduPociagu/dataPrzyjazduPociagu is just YYYYMMDDHHmm

typSkladu can be one of the following: WAGONOWY, ED161, ED160; for some reason, ED250 uses ED160 internally

stacjaOd/stacjaDo is UIC/EPA code, you can find that:

• on wikidata with the following query:

SELECT DISTINCT ?item ?statement ?propertyValue WHERE {
  ?statement ps:P954 "${hafasCode}".
  ?item p:P954 ?statement;
    wdt:P722 ?propertyValue.
  }

where it's property P722 ("UIC station code")

• by using the intercity.pl search api:

curl -A '' 'https://www.intercity.pl/station/get/?q=katowice'

the WAF for intercity.pl blocks curl user agent, but setting an empty one works just fine

	&data=20230716
	&stacjaOd=25
	&stacjaDo=90
	&typSkladu=ED161
	&nrSkladu=

same as above, except:

• nrSkladu is empty for EMUs, but for other cases it's taken from the wagonySchemat field from sklad query for the respective train car
• station codes here are slightly different for non-EMU trains it's just the same as in sklad, but in this example Katowice is 25 and Warszawa Centralna is 90; this is an index of the station in the trip ( starting from 1 and the first station of the entire train trip, multiplied by 5 )
• there's an additional data field which is just the YYYYMMDD date, for some reason

this request returns an SVG where every seat fetches a png file (thanks, devs); in the SVG file there's also a script that handles picking a seat and reveals what some filenames mean:

var p1Img = {
  R: imgServerUrl + '1R.png',
  L: imgServerUrl + '1L.png',
  U: imgServerUrl + '1U.png',
  B: imgServerUrl + '1B.png',
} /* niedostępne miejsce */
var unavailableImg = {
  R: imgServerUrl + '3R.png',
  L: imgServerUrl + '3L.png',
  U: imgServerUrl + '3U.png',
  B: imgServerUrl + '3B.png',
}
/* wybrane miejsce */ var chosenImg = {
  R: imgServerUrl + '2R.png',
  L: imgServerUrl + '2L.png',
  U: imgServerUrl + '2U.png',
  B: imgServerUrl + '2B.png',
}
