Trivia: What did the “L” in Chicago’s “L” Trains originally stand for?
Correct Answer: Elevated
So why is this answer correct? : In 1892, Chicago streets were deeply congested with traffic from horses, pedestrians, and cable cars. In order to mitigate this overwhelming mass of movement, Chicago began building an elevated rail system, nicknamed the “L.” Today, the “L” has 145 stations and 224 miles of tracks that serve nearly 800,000 riders on an average weekday.
