If you happened to see a train running on the Second Avenue subway this weekend – you weren’t dreaming.
After nearly a century in the making, an MTA spokeswoman said the authority began test trains on the famously unfinished line over the weekend, two months before it’s scheduled to open stops between East 63rd and East 96th streets.
Train enthusiast and YouTuber DJ Hammers posted a video of several of the test trains passing through between the two levels of the Lexington Avenue - 63rd Street station on Sunday.
The video shows several trains that don't normally run in the area, including trains for the Brooklyn and Queens-only G line.
"Very interesting operation," Hammers said in the video's caption.
Last month the MTA said it wouldn't begin testing on elevators and escalators at the 72nd Street station until late November, just weeks before a planned Dec. 31 opening. Any glitch at the 72nd station could threaten an on-time opening of the long-awaited line.
The line will eventually run between 125th Street in East Harlem and Hanover Street in the Financial District. The line had been initially proposed in 1919 but work never commenced in part due to the Great Depression.
Work started and stopped intermittently over subsequent decades, and work on the current iteration of the project began in 2007.
