Transfers are not limited to enclosed passageways. The New York City Transit Authority (NYCTA), manager of the New York City Subway, also offers limited free transfers between subway lines that allow passengers to reenter the system's fare control. This was originally done through a paper ticketing system before it was replaced by the MetroCard. Now the only permanent MetroCard subway-to-subway transfers are between the Lexington Avenue/59th Street complex () and the Lexington Avenue–63rd Street station () in Manhattan and between the Junius Street () and Livonia Avenue () stations in Brooklyn. The contactless OMNY fare payment system installed in 2019-2020 supports the same free transfers as the MetroCard does.
