The term "Tube" goes back to the earliest days of deep-level tunnels.
Wasn't the Central London Railway (now the Central Line) dubbed "The
Tuppenny Tube" soon after opening in 1900?

But as a whole I have always referred to it as the Underground. It is
after all run by London Underground. I now find that some people inclding
TfL themselves no refer to the whole system as the tube.

Nothing new in that at all - TfL refer to it as both the Tube and London
Underground, as has been the case for the past three decades.

Some references to the "Tube" in official publicity...
