One of my favorite camping spots. Looking one direction:
Very similar to my case, only the tracks were across the river. You can see the roadbed in the photo.
There must be some public grade crossings in that area. Federal regs. require the horn at all public crossings unless what is called a "quiet zone" has been established. Establishing one usually costs a good deal of time and money, which is why you generally see them in well-to-do communities. Whitefish, MT is a good example. The road that leads to the state park (and passes through a residential area) on the edge of town crosses a busy BNSF line. While the trains still skirt the edge of the park, they no longer blow their horns at the crossing due to establishment of a quiet zone.
