It would be interesting to see a negative bar with station closures as well. And some way to zoom the map would be nice.

As a point of interest, I'll mention Tōgeshita station. A station in the middle of nowhere. Sometimes, a station would exist purely because that's where trains needed to pass one another. Tōgeshita was one of those.

Whenever I passed the station, it was strange, almost a creepy feeling. I think it could have been a great plot for a Japanese horror movie, something in a "Blair Witch Project" style... the old one car train slows to a stop. The door opens, no one dares get off there. Except you, with your portable camera, a cavalier exit from the train. The conductor casts you a side eye with a dead pan 'arigato goziamasu.' The creaky diesel train car slowly pulls away and you're left there stranded for the next few hours until the return train comes around. I wonder what I'll find in the forest just beyond those trees....
