If you live in New York City, chances are you use the subway system daily. Love them or hate them, New York's subway cars are an iconic symbol of the city. But have you ever wondered how those cars came to be?

We did, so we decided to take a trip (via subway, of course, as well as Metro-North rail) up to Yonkers, New York, to the Kawasaki Rail Car Manufacturing Facility, where many of New York's subway cars are completed and readied for service. What we found gave us a new perspective on the way we get to work every morning.
