the S line…

…as in the Shuttle that moves between Times Square and Grand Central.  I took it every day for a full two years at my first job out of college. and now i take it every day this summer for my internship.  and yet i still don’t understand its system.  if you’ve taken it, you know that you wait for a train to arrive on one of three running tracks.  unless, it’s announced on the loud speaker or it’s displayed on a screen, i never know which track the train is going to arrive on.  

but people somehow always know which track to go to so i just follow them, feeling slightly skeptical because i wonder how in the world they know where to go.  do the trains arrive in order?  it’s like something i don’t understand but won’t ever really try to understand… kind of like i didn’t know until sometime in high school that thanksgiving falls on the last thursday of november.
