This map shows you how far you can travel from each station in Europe in less than 5 hours.
It is inspired by the great Direkt Bahn Guru. The data is based off of this site, which sources it from the Deutsch Bahn.
Hover your mouse over a station to see the isochrones from that city.
This assumes interchanges are 20 minutes, and transit between stations is a little over walking speed. Therefore, these should be interpreted as optimal travel times. The journeys might not exist when taking into account real interchange times.
