When I was a Long Islander, it was the LIRR. Now that I am a Southern Californian, it is Metrolink. I admire most about them that they are always on schedule. You can set your watch by their timetable. The San Bernardino Line of Metrolink is incredible, including the F-59PHI's and the Bombardier bilevels. Even the restrooms on board are clean. And if you need to catch the 7:45 into LAUS, at 7:45 there will be a train in front of you ready for you to board. Most of the time you see a few passengers that are running late, running to catch the train.
