Very few things in NYC give you the rush and personal satisfaction like running full speed and catching the train. Depending on the hour and time of day. The cost of missing a train can equal a 10 to 45 minute wait. This wait may be in a smelly underground station with 10 old men sleeping on the platform or a rat or 3 running around your feet.
On the flip side of the coin. Very few things are more painful than preparing to jump on the train and the steel doors slam in your face. It’s the eyes of the people that saw you “almost” law it that hurt the most.
People often wonder why new yorkers walk so fast. It’s because of the cost involved in missing that iron horse.
