Read the neighbor's article. It explains that in full detail. In short, they appear once every 23.5 hours. The timer for that 23.5 hours is reset each time you unload ALL trains at Mr. Bill's station. So if you unload all trains at your neighbor's stations, but do not visit Mr. Bill, you will never have trains arrive ever again.
