Union Square Station: Crossroads of NYC’s Subways

Most people who visit New York City are under the impression that Manhattan’s largest public transportation hubs, aside from the airports, are Pennsylvania Station and Grand Central Terminal. As far as the blend of subway lines and commuter railroads connecting New Jersey, Long Island, and the rest of the Northeast Corridor, those hubs stand as the largest transportation centers in New York City. However, within the New York City subway system alone, one of the busiest and most important stations is Union Square Station. Located beneath the historic Union Square Park, this massive transit hub serves millions of riders every year and connects seven subway lines, making it one of the most vital stations in the entire system.

New York City’s Union Square Station is located at 14th Street and Fourth Avenue in Lower Manhattan. However, don’t let the single address fool you, as the station has multiple entrances and exits spread across several blocks surrounding Union Square Park. Both the subway station and the park share a long and fascinating history that has made them among Manhattan’s most recognizable destinations.

In simple terms, you can get almost anywhere you want to go in Manhattan, Queens, the Bronx, or Brooklyn from Union Square Station. There may be transfers involved, but your journey can begin here. However, depending on which entrance you use, that journey may also require a healthy dose of patience. Union Square Station is huge. Depending on where you enter, your experience can range from a simple MetroCard swipe to navigating what feels like an underground maze.

Certain entrances to Union Square Station leave riders with only one train line to choose from. The entrance at East 16th Street and Union Square East, for example, takes you directly to the 6 train platform, making the decision as simple as choosing uptown or downtown. Enter through the main entrance at 14th Street and Fourth Avenue, however, and you’ll soon find yourself standing at one of the busiest crossroads in the entire subway system. It’s not a place for first-time visitors.

The main Union Square Station features plenty of signs directing riders toward the different subway lines, but somehow it always seems as though the signs disappear just when you need them most. Add in the summer heat, the familiar subway smells, and the endless parade of colorful New York characters, and the experience can be both entertaining and overwhelming.

Union Square Station is the ultimate subway connection point outside Penn Station and Grand Central Terminal, though without the extensive shopping, restaurants, and conveniences found at those larger rail terminals. Union Square Station connects the following subway lines.
