When it comes to the world’s most majestic train stations, New York’s Grand Central Terminal almost always makes the list. Built in 1913, the Beaux Arts depot is the world’s largest in terms of platforms—there are 44 of them serving 63 tracks—and it’s famed for its elaborate details such as the magnificent celestial ceiling mural and the iconic four-faced clock, worth an estimated $10–20 million, in the main hall. But despite being an architectural gem, Grand Central was almost lost to the wrecking ball, like its competitor Penn Station, in the 1970s. But thanks to a push by preservationists and architecture enthusiasts, including Jacqueline Kennedy Onassis, that captivated the nation, the terminal was saved in a landmark Supreme Court case about landmarks (pun intended)—a ruling that celebrates its 40th anniversary in 2018. This year also sees the 20th anniversary of the massive restoration that brought Grand Central back to its former glory. To celebrate these occasions, we’re taking a walk down memory lane and diving into the history of this legendary railway terminal.
