"To build a new transit connection between Brooklyn and Queens, a streetcar may be what the MTA desires.
Transit officials have identified light rail train cars as the easiest way to realize Gov. Hochul’s proposed Interborough Express, which aims to bring passenger service to a 14-mile set of freight tracks from Bay Ridge to Jackson Heights.
Officials since January have also examined using the line for conventional commuter trains like those on the LIRR or Metro-North. The construction of a dedicated roadway for buses is also on the table."

Too bad they can't rebuild the 4th track on the hell gate bridge and run this out to the Bronx. But they are "constraints" for the heavy rail options.
