When the expected tannoy address and departure board listing did not appear, boos erupted.
Hundreds of followers, many dressed in costume, typically attend the event to celebrate the opening of classes at the made-up school of wizardry.
A popular destination for fans, the London station is where the Hogwarts Express is renowned for departing from hidden platform 9 3/4.
The series is owned by Warner Brothers, which has a Potter store in King’s Cross. The company “strongly discouraged” fans from attending and said that the this year’s theatrics would not be taking place.
Many, meanwhile, either ignored the warning or showed up nevertheless.
There was a countdown to 11am with great enthusiasm and phones trained on the departures board.
However, it was all in vain, and following a hopeful hush, a few jeers and boos made their way through the assembly.
The King’s Cross event was canceled without explanation, and it’s not certain if it will return the following year.
There were, however, more Back to Hogwarts events, some of which happened online and at Grand Central Station in New York, where Bonnie Wright, aka Ginny Weasley, made an appearance.
