demolished in the late 1980s, and a new depot was erected opening on November 8, 1992, replacing the old 54th Street Depot (also a former Fifth Avenue Coach facility) which closed the same day. In September 1998, the depot operated a pilot fleet of 10 Orion VI hybrid electric buses. Also that year, it was planned to convert the depot into a compressed natural gas (CNG) facility due to community complaints, but the plan was scrapped due to the high cost of converting such a large facility. Since 2010, Manhattanville Depot is the one of the most greenest bus depots in the city because they only use Hybrid Electric Buses.

Quill Depot fills the block bounded by Eleventh Avenue, the West Side Highway, 40th Street, and 41st Street in Midtown Manhattan (), near the Jacob K. Javits Convention Center, Hudson Yards, and the Port Authority Bus Terminal. The depot was originally the New York headquarters and bus garage for Greyhound Lines. Ground broke on the facility on April 26, 1966. It was designed by De Leuw, Cather, and Associates and built by Turner Construction. It was sold to the New York City Transit Authority in 1996. The Transit Authority renovated the facility at the cost of over $35 million. It opened for NYCT operations in spring 1998 as the Westside Depot, replacing the Walnut Depot and 100th Street Depot (the latter since reopened), and was renamed after Michael J. Quill, one of the founders of the Transport Workers Union of America, on July 13, 2000. The Michael J. Quill Bus Depot had received most of its routes from the defunct Hudson Pier Depot, which closed in 2003. The Michael J. Quill Depot is the largest MTA depot in the city, consisting of three floors and rooftop parking for buses. It is known for a unique "drum-like" structure at the northeast corner of the site, which holds the ramps between the levels. Maintenance facilities are located on the first and second floors. It originally featured training and sleeping quarters for Greyhound drivers. The depot stores around 250 to 350 buses. It is also used for midday layovers for express buses from other boroughs, with additional layover areas nearby in Midtown. The depot was proposed to be relocated
