Yes. She said it to a close mutual friend, and also in my hearing.


But re research: there is a lovely museum in Covent Garden, you can't get much more central. It has maps of which lines were built when. It takes about an hour to go around. There is also a map shop about another ten minutes away that sells historical maps of London. Stanfords is world famous and is in all the guide books. None of this was terribly difficult or required hours of archive research. She really did get very basic things horribly wrong.
