Trivia: Which letter was never used for an NYC subway line?
I
H
K
V
The correct answer is I
So why is this answer correct? : The NYC subway skips the letter “I” because it too closely resembles the number one, which marks a current train that connects Lower Manhattan to the Bronx. The letters “U” and “Y” were also nixed because they sound like the actual words “you” and “why,” which officials thought might be confusing.
