After the leasing of the New Jersey and New York Railroad to the Erie Railroad, the history of Fairmount Avenue station remained rather quiet, with minor changes to the station building and site occurring over the next seventy years. By 1966, the station building had been sold off by the Erie Railroad for private usage as Barbara's General Store and Gifts. The former team track had already been removed from the station, and only the main southbound track and partial yard remained on site with the platform. The station building was already repainted orange along the wood siding and the windows, formerly a dark green, became white. The station continued service through Hackensack as the northernmost of the three stations in Hackensack. In 1976, Conrail took over service of the former line vacated by the Erie Lackawanna (a merge of the Erie and Delaware, Lackawanna and Western Railroads) and service of the station. By 1980, during partial ownership between Conrail and New Jersey Transit, the Fairmount Avenue station remained as a part of the line, but by the 1982 timetables, was removed from service. The station building, although it does not receive any active service, remains standing in its orange and white paintjob. The station building is now a donut shop.
