Isochrones 😍 ! This map shows you how far a 5h train ride will take you, departing from any city in Europe.

You can see the discrepancies in access to rail mobility between cities, how certain high-speed connections are favored, how certain cities are isolated...

This is a followup to this tweet: twitter.com/_benjamintd/st
where I used the isochrones provided by / . Here the methodology is a bit different.

Si vous partez en train de ces villes aujourd'hui à 10h, jusqu'où pouvez-vous voyager avant 16h ?

The data comes from direkt.bahn.guru, which sources it from .
It gives us the direct trains from any station in Europe (as long as it's reacheable from Germany).
From this we can build a graph of stations with travel durations between them.

Since walking and local transit options are not included, we add some connections to the graph to account for buses, walking, biking...
For instance, you can easily walk from Paris Gare de l'Est to Gare du Nord in a few minutes.

Adding the assumption that interchanges / connections are 20 minutes, we can see all the stations that a reachable from a given city in 5h.
(since there is no guarantee that trains will connect perfectly, the map tends to be overly optimistic)

Amazing work Benjamin! Just wondering - is it possible to measure the area of or number of stations within the 5-hr isochrone for each station? Then use this to create a single heat map of the best and worst connected stations across Europe?

Could you now create a heat map showing best/worst connected places in Europe? That would be ace. But also: I'm definitely doing a #RailNatter where I just tour about in this!

Awesome, awesome work Benjamin :) Thank you and Julius for your time and the dope tech. Didn't find a repo so I'll write here for a feature: the ability to click a city, then freely move the mouse without losing the highlighted maps.

I'll open source after some cleanup, thanks for the idea, it's definitely in my to-do ;)

Why "Wien Meidling" and not Hauptbahnhof / Main Station?

You can see any station when zooming in, my mouse just happened to hover over this one :)
I tried ordering the stations somehow but sometimes you'll need to zoom in a little.
I'll try adding a search bar next.
