I just came across this tool, which - after entering a city - shows all other cities to which there is a direct train connection. A color code depicts the travel hours.
Although I'm not quite sure yet on what occasion I can use the tool. But someday the moment will come :D
Btw. there is a Sparpreis search on https://bahn.guru/ with a monthly view ("On which day do I travel cheapest from A to B?"). Unfortunately the links to the store don't work yet.
As an aside, for people who are interested in international train travel - can I recommend https://www.seat61.com - it's a work of love and has helped me loads of times traveling in Europe. Most recently getting a train from the UK to Southern Italy
Why is the German rail infrastructure so shit for such a rich country? Even the Netherlands has a better system. Is it because of the car industry lobbyists?
In itself, I like to take the train to go on vacation. It has a lot of benefits. But one thing I avoid whenever possible is connecting trains. If you don't want to ruin your trip, don't change trains more than once and even then only with a lot of time buffer. If that is not possible, I prefer to make a stopover for 1-2 nights instead and continue the journey on a different day.
The good thing is that you sometimes end up in wonderful places that you don't even have on your radar. This tool had already helped me with that.
Is it nation locked? Or perhaps only counts local trains? Looking at Turin and it doesn't seem to show the high speed links to France. The dotted line stops right at the border.
Is it a direct train though? Maybe you have to change at the border.
It shows international connections from Berlin to Poland for example, so it's not nation locked.
That's really cool! I can't seem to make it work properly though. Sometimes, there's a popup with links to the train connection, but I can't make the popup appear reliably.
