One of the many (many) plot threads in The Amazing Spider-Man 2 is about solving the 'mystery' of what happened to Richard and Mary Parker, Peter's parents. The film opens with their death, a plane crash instigated by an Oscorp agent - but not before Richard manages to send some files to a mysterious location called 'Roosevelt'. It turns out later in the film, after Peter discovers it, Roosevelt is a secret abandoned Subway station Richard was storing some of his work on Spider DNA away from Oscorp in, fearful that it would eventually be used for wrongdoing.
The Secret Underground Train Platform: Walking along bustling Park Avenue, you’d never guess there’s a big secret hidden just below your feet. An abandoned train platform, known as Track 61, was originally built to carry freight from Grand Central Terminal just a few blocks away. As the years went by, it was transformed into an underground station for VIPs to enter the Waldorf Astoria in a clandestine manner. President Franklin Roosevelt was the most famous to take advantage of this perk, and there was even an elevator big enough to hold his bulletproof automobile.
