This playlist from YouTube user hideyasann features more than 100 short clips of trains and train restrooms in Japan. Most of the train videos are of trains pulling into a station, or changing tracks. Most of the toilet videos emphasize the flushing mechanisms—of which there are a surprising variety.
As a rail fan, it's interesting to see what so many different Japanese stations and trains look like. And there's no narration, so it's also interesting to watch these very matter-of-fact clips and think about the visual context they trigger in your head. Men in suits waiting on a platform for a train to change tracks—that's a scene from a serious drama about the inner psychology of a businessman. A shakey clip where the videographer walks towards an arriving train, and a station agent, while breathing heavily—that's totally a scene from a horror movie. I'm honestly not sure what to make of all the toilets.
It's also kind of awesome to just think about the level of obsession that went into this playlist. I'm not really sure what hideyasann is trying to document—Train variety? Train cleanliness? Is he or she just collecting the same footage from as many trains as possible? Whatever the goal, you can clearly see the love and fascination here. There's totally a Happy Mutant at work.
