I think you lost track of the context. You claimed Portland/Seattle is an easy train in response to someone asking if it solves the problem of freight priorities.
Train scheduling is not a simple binary “freight gets priority = problem, passengers get priority = no problem” matter. The GP referred to a specific implementation of a priority system in which passengers could be delayed for more than the base length of their trip, which presumably makes planning around taking the train quite difficult. This is the “problem” with it. Someone else asked if the other areas experience that problem. I said the Portland/Seattle and LA/SanDiego trains do not. That doesn’t mean they don’t have some variety of a prioritization scheme whereby freight often goes in front of passengers, it means they don’t experience the specific problem GP referred to whereby passengers can experience massive delays more than doubling the length of their trip. This in turn makes commenting via train in these areas comparatively “easy”.
