Alternate counterparts of London existed in other realities. These locations shared similarities with London from the Doctor's universe, despite existing in parallel universes or alternate timelines.
Aborted timelines
The Year That Never Was
Much of London's populace was slaughtered by the Toclafane at the start of The Year That Never Was. During the Toclafane invasion a representative from London contacted the Valiant with the message "This is London calling; what do we do?". Martha teleported to a park, from where she could see London burning. She promised "I'm coming back". (TV: The Sound of Drums) Over the course of the year, economic and technological regression occurred massively in the neglected urban centres, with London becoming full of wild dogs. Houses in places like Bexley were used as slave quarters. The enslaved people suffered severe over-crowding, often with many families crammed into a single house.
Having departed from London a year earlier, (TV: The Sound of Drums) Martha Jones returned to the city, supposedly in search of a weapon which could kill the Master. She was captured while staying at slave quarters in Bexley. (TV: Last of the Time Lords)
The Trickster's World
In this reality, London appeared to have become a blasted wasteland, with most buildings reduced to rubble. Big Ben had collapsed, while both Tower Bridge and St Paul's Cathedral appeared to still be standing, albeit partially destroyed. The sky was heavily clouded, and there was a blue-grey tinge to the atmosphere. The only inhabitants lived in a shanty town, where they were forced to mine Earth's remaining resources by Krislok, the Graske servant of the Trickster. (TV: The Temptation of Sarah Jane Smith)
City of the Daleks
Much of London was destroyed in 1963 during the Dalek invasion of Earth. The Eleventh Doctor and Amy Pond found the city in ruins when they landed in Trafalgar Square. The timeline was restored when the TARDIS crew travelled to Skaro to destroy the Eye of Time. (GAME: City of the Daleks)
World without music
After emerging in the 1920s, Maestro sucked the music from the world. By 1963, music was all but extinct. The Fifteenth Doctor and Ruby Sunday discovered a London without music, in which the Beatles recorded uninspired drivel. To view the full extent of a world without music, the Doctor and Ruby travelled forward in time to June 2024 — Ruby's home time — and found London in ruins. The Doctor guessed that without music, the human race went sour, going to war without even knowing why. This timeline was aborted when the Doctor and Ruby returned to 1963 and banished Maestro from the universe. (TV: The Devil's Chord [+]Loading...["The Devil's Chord (TV story)"])
