Not what I would call realtime.
Furthermore, if it takes 3 minutes to communicate a delayed train, and your screen is still trying to create a make-believe of updating your screen every 50 milliseconds, is it real-time?
I would even say that the 1 minute update is more real-time than the make-believe 50 millisecond updates.
