He only works one tube stop away

[gingler]

Could anyone kind enough to explain the meaning of 'one tube stop away' in the stentence?

I've seen a similar phrase'one subway stop away' in one post and understand its meaing, but i still confused with the meaning of 'tube' in the phrase I've mentioned. Does it mean 'very close'?

The complete sentence:
'Anyway, Ravi wanted to say hi. And wanted a catch-up. He only works one tube stop away. So he's going to try and come to the talk.'
From the book named The Midnight Library

In the U.K., the Underground (AE: subway) is also referred to as the "tube."
The author is British.

Note that while the word "subway" is used in British English, its meaning is not at all the same as its meaning in American English. In American English, the word "subway" usually means a rapid transit train that operates, at least in part, under the ground. In British English such a train is called "the tube" or "the underground." The word "subway" in Britain means a pedestrian passage that runs underground (such as might be used to get from one side of a busy highway to another.) In American English, that kind of passage is an "underpass."

Got it, thank you!

The "tube" is specific to London. Glasgow has a subway, Newcastle a metro and I am not sure what people call the Liverpool underground, but it isn't "tube". I can't think of anywhere else in Britain that has an underground railway.
