The Chicago elevated rail system and the biggest piece of junk in the world. Trains are slow, stops are located two blocks apart, trains stop in the middle of the track for no apparent reason and stay there for 5 minutes, stations are old, dirty and disgunting, the fare keeps going up, every once in a while trains crash. There are about 5 stops on different lines with the name "Western" and this could lead to confusion. The stop called "Central" is nowhere near Chicago's downtown. Many of the stations are elevated and don't have stair or escalator access, causing you to have to walk a shitload of steps. Luckily, the crappiness of the system means trains are rarely, if ever, overcrowded.
Tear down that piece of shit and bury it underground, where I at least don't have to look it at it on my way to work.
