Grand Central Terminal in the background
Grand Central is the largest train station in the world by number of platforms.
Grand Central has 75 tracks & 48 platforms
The tracks are numbered according to their geographic location in the terminal building rather than the trains' destinations, because all of the trains terminate at Grand Central.
Fact: Anyone is free to take pictures inside Grand Central. However, if you would be using professional equipment like a tripod, you would need to get a permit through Metro-North's Corporate & Public Affairs Department.
