How kommer Harry till plattform nio och tre fjärdedelar? [stängd]

Han fick lyft till King's Cross Station med Dursleys bil.

”They reached King’s Cross at half past ten. Uncle Vernon dumped Harry’s trunk on to a trolley and wheeled it into the station for him. Harry thought this was strangely kind until Uncle Vernon stopped dead, facing the platforms with a nasty grin on his face.”
“Well, there you are, boy. Platform nine — platform ten. Your platform should be somewhere in the middle, but they don’t seem to have built it yet, do they?” – HP 1 cp.6 p.90

När han hade varit ett tag mellan plattformen 10 och 9 hörde han Weasleys familj och frågade dem hur man kom till plattformen 9¾.

“Excuse me,” Harry said to the plump woman.
“Hullo, dear,” she said. “First time at Hogwarts? Ron’s new, too.” She pointed at the last and youngest of her sons. He was tall, thin, and gangling, with freckles, big hands and feet, and a long nose.
“Yes,” said Harry. “The thing is — the thing is, I don’t know how to —”
“How to get onto the platform?” she said kindly, and Harry nodded. “Not to worry,” she said. “All you have to do is walk straight at the barrier between platforms nine and ten. Don't stop and don't be scared you’ll crash into it, that’s very important. Best do it at a bit of a run if you’re nervous. Go on, go now before Ron.
“Er — OK,” said Harry.” – HP 1 cp.6 p.93
