2.(noun) An unreliable means of transportation. Travel is generally thought to be by rail but can be changed without notice. Travel can also be suspended without notice. Commuters are also subjected to the whims of the mood of the day of the current guard/announcer. Drivers stop at designated stations if they feel like it. Air conditioning? What air conditioning.
