Explanation:

[STC002722] It’s likely that the “city that never sleeps” can be found on the L Train all night long. The New York City Subway is not just one of the oldest rapid transit systems in the United States but also the busiest in the country. When it first opened in 1904, there were probably fewer people using the metro than there are today.
