A three-year advertising deal between NJ Transit and BetMGM was announced at the Secaucus Junction train station and will see the online sports betting company's name added to the Meadowlands Rail Line.
After paying $3m for the advertising arrangement, BetMGM will also have digital and print advertisements throughout the Secaucus station.
Up until the partnership between the two ends, the rail route will be known as the BetMGM Meadowlands Rail Line.
BetMGM Chief Revenue Officer Matthew Prevost commented: "We started three, four years ago in early '19 with about 40 or so people in New Jersey. We now have almost 1,000 employees here in New Jersey.
"Many of our employees start their day with NJ Transit and end their day with NJ Transit, so we really appreciate this opportunity to be a partner."
The rail line transits people across New Jersey, including the Meadowlands racetrack and MetLife Stadium, which hosts New York Jets and New York Giants games, concerts, and other events.
NJ Transit CEO and President Kevin Corbett added: "If we can replicate that appropriately and discreetly throughout the system, that will all go to help keep fares down but also show the company is properly managed.
"We have assets and we should utilize them, that’s what our riders and taxpayers expect."
Last Sunday, over 15,000 people took the train to and from MetLife, up from 13,105 during last year's first home Jets game.
Corbett added that there could be other opportunities in the future for other rail stations including the Newark Broad Street station that serves the Audible headquarters.
