Prior to 1948, most public transportation in New Jersey was provided by the Public Service Corporation of New Jersey, a utility company that also operated the Public Service Railway division. In 1948, the Public Service Corporation was divided into two entities: the Public Service Electric and Gas Company, which inherited the utility operations, and the Public Service Coordinated Transportation Company (PSCT), which inherited the transit operations. PSCT provided service throughout New Jersey, originally using trolleys and then transitioning to trolley buses, and buses. During the 1970s, the New Jersey Department of Transportation began subsidizing the routes of Public Service, now renamed Transport of New Jersey (TNJ), contracting with TNJ and other companies to operate local bus service throughout New Jersey.
