 typically used on elevated lines.

A single Bluebird unit, numbered 8000, was purchased by the BMT as a prototype for a planned fleet of equipment that could operate universally on both standard subway lines and older elevated lines. The BMT expected the Bluebird to preserve its investment in its elevated railway lines without expensive upgrading for heavier subway equipment, while attracting passengers with its interior comforts. Tests demonstrated that its greatly improved operating parameters could have cut significant time from existing elevated train schedules.

Bluebirds were the first PCC rapid transit cars utilizing the advanced running gear originally created for new-design streetcars. In addition to quick acceleration and braking (4 mphps), use of PCC technology meant that Bluebirds could share a significant parts and maintenance base with the Brooklyn

On occasion the train also operated in Brighton-Franklin Ave. Local service and on the Fourth Ave. Local. It probably in those instances operated as an extra behind a regular interval.

After delivery of the Bluebirds, New York City never again purchased any lightweight, articulated or PCC technology rail equipment, nor did it purchase equipment to sustain the lines and portions of the elevated system incapable of operating subway cars. Most of the elevated lines were dismantled between 1940 and 1975.

The remaining Bluebirds were scrapped in 1957.
