At the large-scale level, Penn Station's story illustrates the history of transportation in the 20th century. By examining antiquarian railroad maps, one can view the buildup of the nation's railway system throughout the 19th and early 20th centuries, and observe its decline following World War II when jet and automobile travel became the dominant means of transportation.
