I just moved and I live literally window to a freight train line, unfortunately it scares the crap out of my cats and so I'm trying to find out what the schedule is so that I can close the windows for them, and maybe put a little raspberry pi display screen saying something like "next train arriving in...." Next to my window
You could, but if this is taken from another window in the same building you’ll likely only get ~10 seconds of warning.
If you could put a couple cameras a mile or so down each direction on the track you could get an earlier warning system
This is taken from my window, and I'm not sure how I feel about leaving expensive equipment out in a suburban area for anyone to pick up and run off with
