🚆 A Tube tour

A group of eight British teens are officially the ultimate public transportation enthusiasts. The friends just broke a Guinness World Record by visiting all 272 stations on the London Underground in 18 hours, 8 minutes, and 13 seconds.

🏃 The group, who call themselves "The Amersham Ambushers," were required to visit every London Underground stop using only public transportation. 

• The friends had attempted the challenge twice before, but finally succeeded on their third try, beating the previous record by nearly two hours.

🤔 How did it happen? “A mixture of arguably luck and also a much-improved route,” according to team member Arthur Phillips.
