The Light Rail (or is it a subway?) in Newark, New Jersey 2021

The Newark City Subway is the longer and older of the two segments. The line is a "subway–surface" line which runs underground from downtown to Warren Street, and above-ground north of Warren Street. Before becoming a part of the Newark Light Rail service, it was also known as the #7-City Subway line, an NJT Bus Operations route number carried over from its days when it was part of Public Service's Transport of New Jersey subsidiary. The number still applies internally. (During subway system closures, replacement buses would also bear the route number "7 City Subway.")

The segment is 5.3 mi (8.5 km) long and runs between Grove Street in Bloomfield and Newark Penn Station, a major transportation hub with connections to the PATH rapid transit system to Manhattan, multiple bus routes, and both Amtrak and New Jersey Transit Rail Operations trains.
