Starting Monday, the exterior and interior of all 11 cars will be decorated to look like the famous diner.
Seinfeld last month returned in reruns to an 11 p.m. berth on PIX11 by popular demand after having been moved to the midnight slot last fall. PIX11, Tribune Broadcasting's flagship New York station, has been home to Seinfeld for the past decade.
"For an entire a month, a New York City subway will become the 'Seinfeld 11 Train' in honor of our ongoing commitment to this hilarious show and WPIX," Sheraton Kalouria, chief marketing officer for Sony Pictures Television, said in a statement Thursday. "Now, any time New Yorkers want to know where to find Seinfeld, they just have to think 11 on 11."
The promotion coincides with the first Mets-Yankees Subway Series of the 2014 baseball season, set for the Seinfeld subway's inaugural week of May 12. Fans heading out to Citi Field in Queens on the 7 train will be able to enjoy the Monk's Cafe Seinfeld experience as they prepare for the Subway Series or they can watch the games on PIX11, which is the broadcast home of the Mets.
"Nothing is more New York than Seinfeld, the subway, the Mets-Yankees rivalry and PIX11," said Rich Graziano, PIX11's president and general manager. "Combining all of these is the perfect way to create an iconic New York experience for fans and viewers."
