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
They track them, but they're not all scheduled. If there is enough cargo there they put on a "special" and they will move it between the scheduled trains. Train scheduling and tracking is an art unto itself.
