Yeah the LIRR is stupid busy - "With an average weekday ridership of 337,800 passengers in 2014, it is the busiest commuter railroad in North America."
One way, my wife takes 10 minutes to drive to the station, another 45 minutes on the LIRR, then from Penn another 15 minutes on the subway to her office in Manhattan. The 45 minutes is not even that far east from Manhattan - many people do 60 minutes+. My wife does almost 3 hours a day roundtrip. Contrastingly, I just go downstairs to my office. Of course she makes double what I do too... not a stressful job, just a long commute. On the positive side, she was able to shift her hours so she does 8-4 and is home by 515pm.
