When I was on city council the standard response for this sort of thing was. "Were the train tracks there when you purchased the house?". Answer is always yes. "Did you see the train tracks there when you purchased the house.",, yes,, "So you knew full well there was the possibilities of a train.",, yes,, "So, if you don't like trains and everything associated with them why did you buy that house?",, Usually no answer, but occasionally a stumbling reply that started with, "BUT I didn't think". Mayor's response, "That's right you didn't think". End of issue.
