Since the first tracks were laid in 1848, Chicago has been one of the most important railroad centers in North America. More lines of track radiate in more directions from Chicago than from any other city. Chicago has long been the most important interchange point for freight traffic between the nation's major railroads and is also the hub of Amtrak, an intercity rail passenger system. Today, Chicago ranks second, only behind New York City, in terms of the volume of commuter rail passengers carried each day.
