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.

I believe that light commuter trains should have rubberized wheels. Much of the noise is steel-on-steel action.

If you've ever had a rubber bushing wear out in a car's suspension linkage, you know what I'm talking about: thunk, clang, squeak!
