A week after the CRL's opening, Google Maps just updated their map, but it's showing the CRL incorrectly. Transit still shows the pre-CRL network. AT Mobile doesn't show the train network at all. Catenary has had the correct network since shortly after opening.
Google Maps, showing an incorrect network:
- both the old Western Line and the new East-West Line are shown
- the old yellow Eastern Line is still shown
- Onehunga line doesn't continue to the west (Onehunga-West Line)
- The map is rendered really weirdly, implying that the East-West Line terminates at Karanga-a-HapeTransit app, still showing the pre-CRL network a week after its openingAT Mobile, showing a map without any lines, and with all the stops clustered in a hard-to-use wayCatenary, showing the current network correctly

We try to make the whole network legible and understandable to you, not just funnel you into a journey planner. You can click on any railway or road and see the full routes of any bus or train line on it.

We also show all Auckland bus and ferry routes and live positions — not just trains. Every vehicle on one map in real time.

Congratulations to Auckland on opening the City Rail Link! Te Waihorotiu and Karanga-a-Hape are now open, and trains are running through the tunnel. Catenary Maps shows the new underground stations, full network, and live train positions. Try it at maps.catenarymaps.org or our Android or iOS app.

We've just launched realtime train tracking on our app for MARTA's rail services in Atlanta. We already support MARTA bus. [Note: Service alerts are currently not available. We're planning to introduce service alerts in the coming weeks.]

Other public transportation apps are spying on you and selling your location data! 🕵 Our philosophy is simple: Tracking your bus or train is not consent for you to be tracked. Your journey should be private. We do not sell your location data, in fact, we don't even collect or save it!
We track the trains, buses, metro, trams, ferries, and more... not you.

Catenary Maps, get it on Google play, Launching soon on Apple Store, or web: catenarymaps.org

Headed back to school? 🏫 Try transit! Many agencies offer "school-oriented routes" that are dedicated to students. Anyone can ride these buses, but they usually only run before and after school. Other agencies offer "trippers" that provide extra service. Whatever your commute is, good luck!

On avons envoyé un courriel à la Deutsche Bahn, ils nous ont dit que ce n'était pas open source et que les données n'étaient vendues qu'à certaines entreprises. Ils ont dit que cela pourrait devenir open source dans le futur, mais aucune date n'a été donnée. :(

Deutsche Bahn doesn't want to share their timetable data :( We emailed them last month for data for S-Bahn and Intercity rail (ICE). They said they only sold the data to authorised companies and there's no open license, though they plan to publish open eventually, but couldn't share when.
Email from Deutsche Bahn:

Hallo Kyler

vielen Dank für Ihr Interesse an dem Datensatz.


Der Datensatz ist aktuell nicht kostenfrei erhältlich und kann nur berechtigten Unternehmen zur Verfügung gestellt werden. Wir arbeiten aktuell an der Bereitstellung unter Open Data Lizenz. Hier kann ich jedoch kein Zieldatum nennen. Ich habe Sie auf die Liste der zu informierenden Interessenten gesetzt, falls der Fall eintritt.

Viele Grüße

We've added Toronto's 3 subway lines back onto the map! TTC initially provided us 2 sets of data, a surface streetcar + bus with realtime data, and a schedule without realtime data. Today, we were able to merge both datasets by filtering the plain schedule for only the 3 metro lines.
