London Underground

"Four stops, Harry... three stops left now... two stops to go, Harry..."

- Arthur Weasley on the London Underground

The London Underground is a rapid transit rail system in England that serves the Greater London area as well as several neighboring regions.

On August 12th, 1995, Harry Potter rode with Arthur Weasley on the Underground to get to to the Ministry of Magic for his disciplinary hearing. Arthur was very excited about the Muggle technology such as the escalators and the automatic ticket machines, even though they were out of order.

In December of the same year, Harry Potter again rode a train on the Underground, along with Moody, Tonks, and the Weasleys, to visit Mr. Weasley at St Mungo's Hospital for Magical Maladies and Injuries.

Albus Dumbledore once told Minerva McGonagall that he had a scar above his left knee in the shape of a perfect map of the London Underground.
