The Tram
The Micro
The Tube
The Mover
The correct answer is The Tube
So why is this answer correct? : The London Underground debuted on January 9, 1863, making it the world’s oldest subway system. When the Central London Railway line was added in 1900, it had distinctive round tunnels and a flat two-pence fare, earning it the nickname “Twopenny Tube.” Eventually, Londoners began to use the shortened nickname for the system as a whole.
