Salvatore Fornatora began operating buses in Queens in April 1919 as the Woodside-Astoria Transportation Company,[1] with his first route, the eastern part of today's Q19 route connecting the 103rd Street-Corona Plaza station on the recently opened Corona Line in Corona with Flushing.

[3] After World War II during October 1947, Triboro was acquired by the stockholders of Green Bus Lines, after financial difficulties, but continued to operate independently.

[9] In the early 1990s, three Triboro-operated RTS buses were fitted with special Detroit Diesel Series 92 engines that ran on methanol provided by Air Products & Chemicals.

[12] However, the facility was severely damaged in April 2006 (only 2 months after the MTA Takeover) following an explosion within one of the natural gas lines and destroyed a former Triboro/ ex-Jamaica Bus RTS-04 (see below).

[14] All of the ex-Triboro CNG buses were transferred to Spring Creek and College Point Depots and ran from there up until their retirement.

Nicknamed the "QT (Quick Trip) LaGuardia Express" bus route, it was discontinued in May 1991 due to lower than expected ridership.

[24][25] The one-story brick building covered 12,000 square feet (1,100 m2),[24] and served as the company's main repair shops.

[23] On July 19, 1926, an explosion and fire occurred in the garage's basement, leading to the death of a teenage employee.

Triboro Coach simultaneously operated two garages in Woodside, Queens, in addition to its Astoria depot.

[9][34][35] It was later used in the early 1990s to fuel a New York City Transit Authority demonstration bus from the Casey Stengel Depot[36] and three new Triboro-operated RTS buses fitted with special Detroit Diesel Series 92 engines.

[10] Beginning in 1994, the facility dispatched compressed natural gas (CNG) buses in addition to its diesel fleet.
