Here's where I'm coming from: I wish they would push to make the train a bit quieter. (I'm thankful for having a good network in Chicago) Take a ride to the airport on the blueline in Chicago, fly to London, and when you're on the tube you'll notice a world of difference in the noise level.
It goes from a loud clanking to the hum of the tube.
