**Platform Nine and Three-Quarters** (**Platform 9¾**) was a platform at King's Cross Station in ***London***. Magically concealed behind the barrier between ***Muggle*** Platforms Nine and Ten, this Platform was where Hogwarts School of Witchcraft and Wizardry students boarded the Hogwarts Express every ***1 September***, in order to attend school.

### Location

King's Cross Station, London, England, Great Britain

In order for someone to get onto Platform Nine and Three-Quarters, they had to walk directly at the apparently solid barrier dividing Platforms Nine and Ten. When returning from Platform Nine and Three-Quarters, there was a guard stationed just outside the ticket barrier, in order to regulate exits from the platform through the gate, in order to not alarm the Muggles.

## Overview

> Harry had caught the Hogwarts Express the previous year. The tricky part was getting onto platform nine and three-quarters, which wasn’t visible to the Muggle eye. What you had to do was walk through the solid barrier dividing platforms nine and ten. It didn’t hurt, but it had to be done carefully so that none of the Muggles noticed you vanishing.

In northwestern London lay King's Cross Station, a Muggle railway station that was one of the busiest in the city. It was a perfectly ordinary station, with big plastic numbers over each track and guards who had never heard of the Hogwarts School. However, every 1 September, as the clock overhead approached eleven o'clock, and the ***InterCity 125*** pulled into platform nine, a strange crowd turned the occasional ***Muggle*** head. The crowd was wizarding children, bearing enormous trunks and caged ***owl***s and other unusual pets, making their way toward — and then through — the solid metal barrier between platforms nine and ten.
Through this barrier, of course, lay Platform Nine and Three-Quarters, home of the famous Hogwarts Express. There, a look back at the barrier revealed it was instead a wrought-iron archway with the words "Platform Nine and Three-Quarters" on it. Over the scarlet steam train's billowing smoke, there was a sign announcing that the Hogwarts Express would depart at eleven o'clock. The platform also had a distinct smell — one which lifted the spirits of young wizards who, like Harry Potter, look forward each summer to the start of term.
Though the platform was normally only used six days a year (round trips for the beginning and end of term, as well as the Christmas and Easter holidays), the platform on those days was awash with activity. Steam from the scarlet engine flooded the platform as ***cat***s wound their way around the wizards' legs and ***owl***s hooted to each other, as hoardes of students and parents moved around through the steam "like dark ghosts", their voices carrying through the mist.
Finally, at 11:00, a whistle sounded announcing the train's departure, and the hiss of the pistons filled the platform as the train began to move, creaking out of the station as family members stood on the platform and waved their children off to school. Nobody returned to the platform, then, for months — until the end of term, when it once again filled with wizards and a wizened old guard sat by the archway back to the Muggle world, making sure everyone got home without attracting too much attention.

## History

### Early history (1850s–1971)

 File:Tumblr m2v0ld1i5m1qg1krko6 250.gif
The brainchild of ***Minister*** ***Evangeline Orpington*** in the ***1850s***, Platform Nine and Three-Quarters was the first of the concealed wizarding platforms at King's Cross.
After the Ministry of Magic had acquired the Hogwarts Express, under Minister Ottaline Gambol in ***1830***, they also built a railway station at Hogsmeade, as a necessary adjunct to the train. The Ministry, however, refrained from building a station in the middle of London, as that would stretch even the Muggles' notorious determination not to notice magic even when it was exploding in front of their faces. It was only after Minister Orpington was appointed to the office (***1849***-***1855***) that a solution was reached: a concealed platform would be added to the newly Muggle-built King's Cross Station, accessible only to witches and wizards. There is no information on how exactly Hogwarts students were travelling during the period after the acquisition of the Hogwarts Express and the creation of the Hogsmeade station and before the creation of Platform 9¾ in the ***1850s***.
While the solution proved a good one, there were always some minor issues, such as witches and wizards dropping suitcases full of biting spellbooks or ***newt*** spleens all over the polished station floor, or disappearing through the solid barrier a little too loudly. To prevent any serious breaches of the ***International Statute of Wizarding Secrecy***, there is usually a number of plain-clothed Ministry of Magic employees on hand at the station, to deal with any inconvenient Muggle memories that may need altering.

On 1 September ***1971***, Eileen Snape took her eleven-year-old son, Severus Snape, to board the Hogwarts Express via this Platform. Muggles Mr and Mrs Evans also took their witch daughter, Lily Evans, there along with her Muggle sister, Petunia. While the parents looked around the platform with an air of wholehearted enjoyment, the two sisters argued and Petunia ended up calling her sister a freak.

### Later history (1991–2017)

Harry Potter first used Platform 9¾ on 1 September 1991. Not knowing how to get into it, and recognising the ***Weasley family*** as a family of wizards, he asked Molly Weasley how to access it. As Harry crossed the Platform, he passed by a round-faced boy telling his grandmother he had lost his toad, and a boy with dreadlocks showing a tarantula to his peers.
In June 1992, at the end of the school year, Harry and his classmates returned to their homes via the Platform. Harry was picked up by Vernon Dursley.

On 1 September 1992, Dobby the House-elf blocked the magical barrier dividing Platforms Nine and Ten in order to prevent Harry Potter and Ron Weasley from attending school. Consequently, they decided the only way to get to Hogwarts was to steal Arthur Weasley's Flying Ford Anglia and fly it to the school. When the school year ended, the students returned to the Muggle world via the magical gateway in the platform.

## Behind the scenes

* In the books, the barrier that leads to the platform is described as being made of metal. In the films, however, the barrier is a brick wall.

### Author's comments

"*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.*
*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.*"
