Trivia: Which of these was invented due to the booming railroad industry?
Labor Day
U.S. standard time zones
Reclining seat
Zippered suitcase
The correct answer is U.S. standard time zones
So why is this answer correct? : The introduction of rail travel changed how quickly people could cover large amounts of distance, which also created some new challenges in scheduling. In the 1800s, there were literally hundreds of different local time zones across the country, making coordinating long-distance travel nearly impossible. On November 18, 1883, United States railroads adopted four standard time zones: Eastern, Central, Mountain, and Pacific. “Railroad time” was slowly adopted nationwide, and in 1918, Congress finalized the Standard Time Act.
