There is a screen on the wall by the door to the platform that has alll the upcoming trains and their scheduled arrival and new arrival should they become delayed. Also I would simply advise you to use the Amtrak app where you can at any time of your choosing go to the train status bar and put in the info for your train to check its progres. Through this same app you can earn rewards points, book or change travel, and check the status of other trains and connections.
Just ask at the customer service desk or listen to the announcements. If there will be a delay, they will let you know as soon as they know.
