Some 600,000 commuters, riding Amtrak, Long Island Rail Road and New Jersey Transit, now suffer Penn Station every day. That makes it probably the busiest transit hub in the Western world, busier than Heathrow Airport in London, busier than Newark, La Guardia and Kennedy airports combined.
To pass through Grand Central Terminal, one of New York’s exalted public spaces, is an ennobling experience, a gift. To commute via the bowels of Penn Station, just a few blocks away, is a humiliation. — Michael Kimmelman, nytimes.com
