The MTA may have a magical new subway line.

The 9 3/4 symbol showed up on a Union Square subway sign.

For those who haven't read the Harry Potter books or seen the movies, that's the number of the train platform Harry and his friends use to travel to the Hogwarts school.

The MTA says it had nothing to do with the sticker.
