Maybe I'm getting old, but I remember a sitcom that lasted only a season or two during the late 80s or early 90s and took place on board a Metro North train. Now as i recall it was either a Hudson or Harlem Line train as the M1a or M3, had the blue and white stripes on the end of the car. I believe that the show was called "Tickets Please" (but my memory might be failing me). Does anybody else remember this show?
