The Jerry O'Mahony Diner Company, based in Elizabeth, New Jersey, was a prominent producer of roadside diners from 1917 through 1952. Having manufactured approximately 2,000 prefabricated metal diners—surpassing all competitors—the company was known for its elongated, narrow designs that were frequently confused with railroad cars. Their slogan declared, "In our line, we lead the world."

History

Jerry O'Mahony (1890–1969), hailing from Bayonne, New Jersey, is recognized by some as the pioneer behind the creation of the first "diner." In 1912, Jerry collaborated with Daniel O'Mahoney and John Hanf to construct their initial lunch wagon. This unit was sold for $800 to restaurateur Michael Griffin and operated at Transfer Station in Hudson County. This event marked the beginning of New Jersey's flourishing era in diner manufacturing.

By 2022, about 20 O'Mahony diners continue to function across the United States.

Initially opened as "The Princeton Diner" on Route 6 in Swansea, Massachusetts, it was later moved to Newport where it underwent several name changes before adopting its final title under new ownership in 1998. The diner ceased operations to allow construction of a Seasons Market and gas station. In October 2022, it was sold and transported to New Hampshire where new proprietors intend to reopen it as a dining establishment.
