The trains are only one part of the puzzle. Where I live in Brooklyn I can walk 15 minutes to two different subway lines (DR!), but I can also bike entirely, take the ferry to two different stops that then either travel on a third subway line or let me bike share the remaining 15 blocks, drive to work in an emergency via 2 different bridges or a tunnel, or take the local car service either entirely on the same route (or Uber taxi) or half way to a fourth subway line. Amazingly all of these combinations result in the same 35 minute door to desk commute. The redundancy in the face of bad weather or emergencies is what really pays off in the end when you must get to work. If you live on a far away train line you do have public transportation, but way fewer options if something happens to take out the train (failure, snow, flooding, etc.)
