I want to know the answer to the following question:
Which station is known as the world's biggest railroad station?
All the background I'm provided with is that "The New York City Subway is also the busiest metropolitan rail transit system in the Western Hemisphere, with 1.75 billion passengers rides in 2014, while Grand Central Terminal, also popularly referred to as "Grand Central Station", is the world's largest railway station by number of train platforms.". Is that enough to answer the question?
Answer: yes
