SoNo Switch Tower

SoNo Switch Tower is a preserved switch tower in Norwalk, Connecticut, in the United States. It was originally constructed in 1896 by the New [York, New Haven and Hartford Railroad] to control switches at the junction between the New Haven Line and the Danbury Branch. The tower operated until 1986, when it was decommissioned by Metro-North Railroad following the centralizing of dispatching at Grand Central Terminal in New York City. It has been preserved as a museum.
The museum includes a webcam, run by VirtualRailfan, allowing viewers to watch trains passing the tower on the Northeast Corridor; it has been noted for its popularity among railfans online.
