It’s easy to understand why the Amtrak route between Philadelphia and New York is so heavily traveled. Motor vehicle traffic is subject to congestion and highway tolls, and drivers can get easily fatigued trying to stay alert amidst the alternating stress and/or boredom that can accompany traffic and congestion. Train passengers, in contrast, don’t have to worry about the duty of care owed to other motorists. They can sit back, relax or do other activities while traveling in comfort.
