London Underground (Aldwychverse)

What if Aldwych ended up becoming not a "ghost station", but a major interchange? What if the Elizabeth Line was completed on time for the 2012 Olympics? And what if several failed projects (some familiar to Tube geeks, such as the Northern Heights, Fleet line, and Chelsea-Hackney line; others more obscure, such as the Central line loop and Kearney High-Speed Tubes) had gone through?
