The Chicago L is the rapid transit system serving the city and some of its surrounding suburbs in the U.S. state of Illinois, with L being short for elevated. It is the fourth largest rapid transit system in the United States in terms of total route length (at 165.4 km), and the third busiest rail mass transit system in the United States after the New York City Subway and Washington Metro. Chicago's "L" provides 24-hour service on some portions of its network, which came in very handy when returning from the United Center after seeing the home team beat the New York Knicks. Like most metro stations in the U.S. it has utilitarian style and suffer from varying degrees of decay, which seems a bit alien to me, but I'm sure it makes sense when dealing with a massive network and a shortage of funds. Thankfully there are a few exceptions which I will cover soon.
