On May 19, 1987, WCDOT officially named the bus service "The Bee-Line System" with a 'bee-in-flight' mascot drawn by cartoonist Jack Davis.

[2][3] The Westchester County Department of Public Works and Transportation currently contracts out to two private bus companies to provide service in Westchester County and the surrounding counties: Yonkers-based Liberty Lines Transit, Inc., the main company that either bought out or obtained franchises from the other twelve bus companies over the years, operates buses on all but three bus routes; and Cortlandt Manor-based P.T.L.A.

There is no service county-wide on two days of the calendar year, Thanksgiving (the fourth Thursday in November), and Christmas (December 25).

The system's 64 routes are mostly concentrated in the more urban southern portion of the county, with the cities of Mount Vernon, New Rochelle, and Yonkers receiving a high frequency of service.

Service in the northern portion of Westchester is sparse and is concentrated near slightly populated areas such as Mount Kisco, Ossining, or Peekskill.

Areas such as Lewisboro, North Salem, and Pound Ridge receive paratransit service only.

Dollar bills, passports, and ticket books were no longer accepted for fare payment after this date.

The Westchester County Department of Transportation states that "OMNY is targeted for introduction on the Bee-Line Bus System beginning in 2022 at the earliest."

07.501 (hev) Industries 05.501 In February 2020, it was announced that Westchester County's Bee-Line Bus fleet would be expanding with 78 hybrid-electric 60-foot buses (all delivered by summer 2020), 106 hybrid-electric 40-foot buses and two 40-foot battery-electric buses – all built by New Flyer Industries – under a plan to have the entire transit bus fleet running on either fully electric or diesel-electric hybrid technology by 2025.
