I have another fun project idea that I'm not going to realize.
What I'd love to have is a heat map of "how soon can I get there". One where I select my train station, and get a map of all train stations I can reach within N hours, each marked with the earliest arrival time and colored by how late I'll get there. Including all the reasonable transfers.
Say, the first train from here goes to Konin, so I get its arrival times marked on all stations towards Konin. Then, I can transfer to a few trains in Poznań, so I get their arrival times on their respective stations. And then all the transfers there, and so on.
So what I'd get is a pretty colorful map, with arrival time getting later with distance, except for major stations where IC trains get earlier than suburban trains, and then backwards from major stations where I can get via IC and then change into suburban going back. It would be such a cool experiment!
And honestly, I could start playing with it even with a partially automated tool: one that lets me select a given train and updated the map if it arrived somewhere earlier than I had before.
