There actually is a secondary system to the Paris Métro that runs faster and makes fewer stops called the Réseau Express Régional: http://en.wikipedia.org/wiki/RER

I found this part of the Wikipedia article especially interesting:

> Used for leisure journeys, the RER has had a major social impact. By bringing far-flung suburbs within easy reach of central Paris, the network has aided the reintegration of the traditionally insular capital with its periphery.

The RER is a bunch of separate lines; of course when you have two lines covering similar routes one can (to a certain extent) relieve the other. What NY has is different: 4-track lines everywhere, allowing them to do maintenance on one track pair while keeping the other running.

That's what suburban train systems usually do, isn't it? You get on the train in the middle of the city and in 40 minutes there's lakes and forests and everything.
