In the Pottermore article on Platform 9 and 3/4 it's mentioned that other fractional platforms exist (7 1/2, for instance). Is it ever stated elsewhere where these platforms lead? Perhaps you could get a connection from your hometown by accessing one of these platforms?

    It's a shame Rowling has apparently never been to Kings Cross station. The only walls are between 8 and 9, 4 and 5, and the new 0 and 1. There's no wall between 7 and 8, or even 9 and 10. May 1, 2012 at 10:11

  • JKR says in that very article that she hasn't concretely determined where the other platforms go. May 1, 2012 at 18:05

    @DanielRoseman King's Cross has renumbered its platforms more than once in the last couple of decades.

    @Daniel Roseman You are assuming that in all train stations the tracks are numbered sequentially. Once I took a train from 30th Street Station in Philadelphia, PA to my suburb at Chalfont. But due to a problem the train stopped at Suburban Station and we had to get on another train on another track. And there I noticed that track number one was not at one side but between two tracks with higher numbers. So maybe Platform 9 & 3/4 is in a wall between 8 and 9, for example, being numbered out of sequence. Feb 7, 2021 at 17:59

1 Answer 1


Dumbledore smiled at him. ‘We are in King’s Cross, you say? I think that if you decided not to go back, you would be able to ... let’s say ... board a train.’

‘And where would it take me?’

‘On,’ said Dumbledore simply.

Deathly Hallows - page 578 - UK - chapter 35, King's Cross

Perhaps the ¼ and ½ platforms simply lead On . . . wherever and whatever On may be!

Barring Word of God, I think this is the closest canon reference we're going to get to the other trains. Yes, I realize Dumbledore is speaking metaphorically. And yes, I realize the trains are not specifically described in canon.

On is just an idea. :)

ETA: This kept niggling at me, so I signed into Pottermore and checked the information on Platform 9¾ . . . and I found something. JKR perceived other trains leaving from other fractioned platforms. She thought one might be like the Orient Express, while others would be used on special occasions to take witches and wizards to one-off events, like a concert (or maybe even a magical creatures zoo or circus!)

Sayeth You-Know-Who:

In choosing the number of the concealed platform that would take young witches and wizards to boarding school, I decided that it would have to be a number between those of the Muggle platforms - therefore, it was clearly a fraction. This raised the interesting question of how many other fractional platforms lay between the whole-numbered platforms at King's Cross, and I concluded that were probably quite a few. Although these are never mentioned in the book, I like to think that it is possible to take a version of the Orient Express off to wizard-only villages in continental Europe (try platform seven and a half), and that other platforms may be opened on an as-required-basis, for instance for large, one-off events such as Celestina Warbeck concerts (see your ticket for details).

The number nine and three-quarters presented itself without much conscious thought, and I liked it so much that I took it at once. It is the 'three-quarters' that makes it, of course.

    See my edit -- I went into Pottermore and found the Word of God :)) May 2, 2012 at 8:07
  • Isn't this answer basically just restating the question? OP already quoted from and linked the same source you cite.
