Trivia: Where was the world’s first underground subway system built?
Correct Answer: London, England
So why is this answer correct? : London’s Metropolitan Railway opened on January 10, 1863, marking the world’s first underground railway. The line traveled from Paddington (then Bishop’s Road) to Farringdon Street, the first of many routes that would be built over the next century. On December 18, 1890, the underground metro set another first: the first underground electric railway in the world.
