Chicago has the Metra which runs from all the major suburbs to Union Station and only that one station. There is also the El which runs over the roads but I've only been on that once and don't want to again. Not clean at all. As for the Metra, I've been on it many times going into Chicago but it's takes 2 hours while to drive takes 1 or less since it has to stop at every single station if your not on it during rush hour.

When I was in DC we traveled alot of the subway there and it was great. You get around to places faster than walking and since the station was only 2 blocks from our hotel it was easy to get to. Not sure how much it cost though. It also was great since it was cold down there and up above was 100+ (walking down the national mall sucked that day, I never knew it was that long and the heat made it worse)
