But this being the 21st Century somebody in T management was not amused.
A dispatcher injected a bit of unauthorized whimsy into the LED signs at the Park Street Station. He programmed them to scroll the carol's lyrics.
These signs were supposed to tell us how many minutes before the next train but after more than 2 years they still only tell us a train is arriving ( like we need a sign to tell us that )
Hopefully the T will not discipline this worker.
