==== Geodata ====


licensed under [[https://creativecommons.org/licenses/by/3.0/at/deed.de|Creative Commons Namensnennung 3.0 Österreich]]

Contains
  * rail tracks and 
  * train stations/stops

GeoJSON and Shape EPSG: [[http://spatialreference.org/ref/epsg/31297/|MGI Austria Lambert]]!





Useful attributes:

**NAMECAT** distinction between train station (Bahnhof) and stop (Haltestelle)

**CROSSSECT/CROSS_NAME** distinction between  nach Eisenbahnstrecke single-track (eingleisig), double-track (zweigleisig), station area (Bahnhofsbereich) and stop area (Haltstellenbereich)

GTFS, updated quarterly (as of April 2019)

I created a  {{ ::oebb-gtfs-20190404.zip |gtfs archive}} and checked it with [[https://github.com/google/transitfeed/releases|transitfeed 1.2.16]] (latest release available at that time):


**TLDR: looks usable (but be sure to look into the block_id issue if you plan to use this column).**



Long version: no errors, 4060 warnings.

**383 Duplicate IDs** in [[https://developers.google.com/transit/gtfs/reference/#transferstxt|transfers.txt]]: these appear to be walking times within larger stations such as Innsbruck HBF or Salzburg HBF.
Since additional columns (from_trip_id,to_trip_id) have been added (which are not documented in GTFS for transfers.txt), these must be changing times for specific trips.



**59 Invalid Values** in [[https://developers.google.com/transit/gtfs/reference/#routestxt|routes.txt]]: can be ignored, all flagged values  
  * 101
  * 102
  * 103
  * 106
  * 109
are contained in the [[https://developers.google.com/transit/gtfs/reference/extended-route-types|extended route types]]. 
Also minor warnings about route_long_name and route_short_name.

**1475 Overlapping Trips In Same Blocks** in [[https://developers.google.com/transit/gtfs/reference/#tripstxt|trips.txt]]: "Trip 348 and trip 349 both are in the same block 270 and have overlapping arrival times."\\
The (optional) block_id field identifies the block to which the trip belongs. A block consists of a single trip or many sequential trips made using the same vehicle, defined by shared service day and block_id.\\


**2139 Too Fast Travels**: can be ignored since feedvalidator flags everything faster than 100km/h.


**4 Unrecognized Columns** in [[https://developers.google.com/transit/gtfs/reference/#stopstxt|stops.txt]]: can be ignored, the column platform_code is not defined for [[https://developers.google.com/transit/gtfs/reference/#stopstxt|stops.txt]]


==== Ticket shops ====

JSON with 1109 shops.

Licensed under Creative Commons Attribution 4.0 International (CC BY 4.0).

Contains loads information like opening hours, accessibility.

===== Combining datasets =====


I tried matching the ticket shop JSON with GeoJSON stops:

GEOJSON\\
**pk_bfnr:** nationale Bahnhofnummer, z.B. 1114\\
eva_bfnr: internationle Bahnhofnummer, z.B. 8100002. 


JSON\\
GIP_OBID ID aus der Graphenintegrations-Plattform GIP, e.g. 15532299337\\
**EXTERNALID** Betriebsstellen-ID der ÖBB-Infrastruktur AG, e.g. 1235



but externalid to pk_bfnr does not produce valid matchings:

2511: FEATURENAME BST Wien Westbf 

2511: 'bfname': u'Gobelsburg'
