I took the little train and then walked across to avoid riding around the other terminals in the loop and because I wanted to see the new international terminal. There was no risk whatsoever to life and limb. It was a pleasant and safe walk, but a long way if one has much luggage. The point is that you can cut across rather than taking the train the entire way, especially if some of the little trains aren't operating or if there's service in only one direction around the terminal loop.
