Hello, Pasha! Im glad to see you again! I would like to know more about the London underground, I hope you will not mind.
Yes, of course. I will be happy to answer your questions!
So, I know that the London underground is old, isnt it?
Yes, it is. The London underground is the oldest in the world! The first stations were opened in 1863.
How many underground lines are there at the moment? And are they colorful?
11 lines and each of them is marked on the map with its own color. The underground map can be taken free of charge practically at any station.
And how is the underground itself and the payment?
The London underground is divided into zones 1 through 6. Zone 1 is the very center of London, and 6 is already a remote suburb.
The cost of travel by subway depends on what zones you travel within.
Any interesting facts?
By the way, at many underground stations you can hear the phrase that has become the London underground card: Mind the gap. Or Please mind the gap between the train and the station. This phrase is a reminder that there is a gap between the train and the platform.
Thank you very much, Pasha!
Youre welcome.
