Listed with the Japanese description densha on, meaning electric train sound, this clip is a straightforward field style recording rather than a clip from a film or show. Sounds like this spread through sound effect libraries and soundboards because they solve a practical problem for editors who need clean railway ambience without recording it themselves. The long, uninterrupted pass by makes it especially reusable for videos, animations, school projects and indie games, where a short horn or crossing bell alone would not sell the sense of a real train moving through a place.
