The Jerry O'Mahony Diner Company of Elizabeth, New Jersey, was a manufacturer of roadside diners from 1917 to 1952. The company produced some 2,000 of the long, narrow, primarily metal buildings, perhaps more than any other firm.[1] Prefabricated in a factory and trucked to their locations, the diners resemble and are often confused with railroad rolling stock. The company's motto was "In our line, we lead the world".
