You are correct about the 1-800 number and the mile marker at each crossing. I’ve spoken to people that tried calling it before and they made it sound liked it’s impossible to reach someone. I personally have not tried calling.Also... don't they normally have signs at rail crossings with a 1-800 number and a unique identifier? I hear those are pretty effective at getting anything on that line stopped ASAP. Not a guarantee, but a whole lot better than waiting for the engineer to see you and decide he can at least slow the train down even if he doesn't have time to stop any more.
