I’ve been in one of those trains that had to wait, and it was definitely frustrating. However, you are incorrect, passenger rail has priority. What rail companies have done, however, is to make their cargo trains too long to fit onto the pull off rails provided to them, meaning, despite the fact that they are legally obligated to allow the passenger trains to pass, functionally, they’ve bypassed that law and the federal government has put no effort into correcting that behavior.
