Popular Science – Traveling by train can be smooth and uneventful—or absolutely miserable. This spring, a series of derailments and delays caused by aging equipment at New York Penn Station snarled travel at the busiest rail hub in the North America, culminating in a plan for much-needed repairs that will disrupt commuters’ schedules for months.
